Abstract:
Binary Phase Shift Keying represents the simulation results of binary digital modulation schemes. Here for BASK and BPSK modulation techniques use FPGA algorithm. If multiplier block is used for multiplication bit stream with carrier signal, used time will rises. In addition using multiplier block obtained simulation results were analyzed and compared to other simulation results. Source consumptions of FPGA-based BASK modulation technique and BPSK modulation technique were compared. Also, for different modulation algorithm, source consumptions of BASK and BPSK modulation technique were analyzed using VHDL. Designed modulators using VHSIC (Very High Speed Integrated Circuit) Hardware Description Language (VHDL) was realized on high speed FPGA (Field Program Programmable Gate Array). Because for used modulation technique data rate transfer is fairly important in wireless communication systems. The highest speed data rate transfer can be realized using fiber optic cables. In addition, BER (Bit Error Rate) of BASK and BPSK modulator was compared using MATLAB simulation program. Binary data rate is same for BPSK and BASK. BPSK and BASK modulations were designed on FPGA using VHDL hardware description language.

Abstract:
Wireless communications are among the rapidly growing fields in our current life and have a massive effect on every aspect of our everyday life. In this paper, the performance of the various digital modulation techniques (BPSK, DPSK, QPSK, and QAM) based wireless communication system on the audio signal transmission through the additive Gaussian Noise (AWGN) channel is assessed on the basis of bit error rate (BER) as a function of the signal-to-noise ratio (SNR). Based on the results of this study, BPSK modulation outperforms the DPSK, QPSK, and QAM modulation strategies in the MIMO MC-CDMA VBlast based wireless communication system. The digital modulation of QPSK shows the worst performance in audio signal transmission especially in comparison to other digital modulations. It is clear from the current simulation study based on MATLAB that the V-Blast encoded 4×4 MIMO MC-CDMA wireless system with minimum mean square error (MMSE) signal detection and 1⁄2-rated convolution and cyclic redundancy check (CRC) channel encoding strategies show good performance utilizing BPSK digital modulation in audio signal transmission.

Abstract:
In this paper, the bifurcation parameter of the chaotic map is estimated accurately by utilizing the ergodic properties of a chaotic dynamical signal. Binary Phase Shift Keying Ergodic Chaotic Parameter Modulation (BPSK-ECPM) scheme is used to modulate the information signal in the bifurcating parameter of the chaotic map. A mean value estimation technique is used at the receiver to retrieve the original information accurately. This method minimizes the computational complexity of the receiver; thereby, reduces the total manufacturing cost. Simulation results confirm that, in AWGN channel and at bit error rate (BER) of 10-3, BPSK-ECPM achieves gains in Eb/N0 of about 0.7dB and 5dB in comparison with conventional direct sequence spread spectrum with BPSK modulation (DS-SS BPSK) and conventional ergodic chaotic parameter modulation spread spectrum (ECPM-SS) systems respectively. The results also confirm that in Rayleigh fading channel and at BER of 10-3, BPSK-ECPM achieves gains in Eb/N0 of about 6.3dB and 1.6dB in comparison with DS-SS BPSK and ECPM-SS systems respectively, which make BPSK-ECPM an ideal candidate for the intelligent transportation system (ITS).

Abstract:
The application of OFDM technology is still not fully implemented in the Telecommunication Study Program at State Polytechnic of Malang. This is because the application of this technology is applied to hardware. However, this can be overcome by simulating the OFDM technology through software. From the application of the system into the program by entering the predetermined parameters, the BER value can be compared to the predetermined parameters. Bit error that appears in the application of the OFDM Multi user system for bit error in BPSK Modulation with AWGN and Rayleigh Fading channels appears bit error respectively with an average of 9 bits and 14 bits at 11 dB SNR. Whereas in the QPSK modulation with AWGN and Rayleigh Fading channels, each bit error appears with an average of 13 bits and 18 bits on the SNR of 14 dB. Furthermore, in the calculation of bandwidth efficiency in the frequency allocation of 20 MHz for BPSK modulation, three values ??of bandwidth efficiency are obtained, among others, 1 bps / Hz in theory for practical, namely the code rate ½ is 0.3 bps / Hz and the code rate ¾ is 0.45 bps / Hz. While the QPSK modulation also obtained three values ??of bandwidth efficiency, namely, 2 bps / Hz in theory for practical, namely the code rate ½ is 0.6 bps / Hz and the code rate ¾ is 0.9 bps / Hz.

Abstract:
Innovations in the field of wireless communication are growing very rapidly in line with the behavior of modern societies that have high mobility, need of the flexible services, easy access, and high speed data transfer to facilitate any activities of its users. The needs of every user of any variety are more than just voice, video, data transfer, up to a demanding streaming multimedia capabilities and reliability of the communication system used. One of the factors that affect the quality and speed of data transfer in wireless communications is modulation. The development of technological modulation allows data transfer rate to become faster, more resistant to noise, and have high security (encryption) in order to secure data sent over the lead. The implementation of digital modulator PSK (Phase Shift Keying Modulation) and QAM (Quadrature Amplitude Modulation) on FPGA is designed to simplify the design of a hardware by representing the input which is prepared by using the VHDL programming language. The input will be programmed by logic gates contained in the FPGA into a circuit that functions as a digital modulator. This device can map the input bits into a modulator output that has been mapped in accordance with the coordinates of the constellation. The expected results of the implementation are three types of digital modulator, namely: BPSK, QPSK and 16-QAM to be implemented on FPGA Xilinx Spartan-6 XC6SLX45 CSG324C; modulation type to be used can be selected by entering input on the programs implemented in the FPGA. In the design used input from laptop devices with UART interface and data types for input is ASCII 8 bit for later analysis simulation results modulation of the input to each modulator using Modelsim for simulation design and Chipscope for simulation system design implemented in the FPGA.

Abstract:
Digital modulation increases information capacity, data security, and system availability while maintaining high communication quality. As a result, digital modulation techniques are in higher demand than analog modulation techniques due to their ability to transmit larger amounts of data. Amplitude Shift Keying (ASK), Frequency Shift Keying (FSK), Phase Shift Keying (PSK), Differential Phase Shift Keying (DPSK), and Quadrature Amplitude Modulation (QAM) are critical components of current communications systems development, particularly for broadband wireless communications. In this paper, the comparison of bit error rate performance of different modulation schemes (BPSK, QPSK, and16-QAM) and various equalization techniques such as constant modulus algorithm (CMA) and maximum likelihood sequence estimate (MLSE) for the AWGN and Rayleigh fading channels is analyzed using Simulink. BPSK outperforms QPSK and 16-QAM when compared to the other two digital modulation schemes. Among the three digital modulation schemes, BPSK is showing better performance as compared to QPSK and 16-QAM.

Abstract:
A method of generating constant envelope BPSK compatible modulation formats is described in which spectral containment is achieved via controlled phase rotations. These Shaped BPSK modulations can be considered BPSK/CPM hybrids. The instantaneous phase transitions of BPSK are tempered to become the continuous phase rotations of CPM. The SBPSK modulations described above are compared with classical BPSK as well as a Shaped BPSK modulation specified by the Joint Chiefs of Staff for use with Department of Defense 5kHz UHF SATCOM channels. It is shown that the use of SBPSK modulations can allow significant increases in the data transmission rate without exceeding the spectral "envelope" of a lower rate BPSK signal. Analysis also includes fractional out of band power curves for the modulated signals before and after transmission through a bandpass hard-limited channel. Equivalent SNR's are generated to quantify the simultaneous effects of decreased adjacent channel interference at the expense of I channel energy. Finally, probability of error curves vs SNR are presented for BPSK and SBPSK modulations transmitted through a band-limited and hard-limited channel.

Abstract:
La détection d'objets fixes ou mobiles est largement utilisée en milieu industriel pour des applications de contrôle dans le domaine de l'automatisation des process. Plusieurs technologies (inductive, photoélectrique, ultrasons, etc. ) partagent le marché de la détection d'objets. Chacune de ces technologies possèdent des contraintes d'application liées souvent à leurs principes physiques. Au contraire, le domaine des hyperfréquences et particulièrement la technologie Radar offre des performances meilleures dans des environnements hostiles. L'objectif de cette thèse est d'explorer toutes les solutions techniques apportées par la technologie Radar afin de concevoir un détecteur d'objets fixes ou mobiles satisfaisant les contraintes du milieu industriel. Dans le panel des technologies Radar, les efforts sont souvent consacrés à la détection d'objets mobiles. Certaines de ces technologies sont capables de détecter des objets fixes mais avec une résolution qui demande une bande de fréquence importante. Ces technologies s'avèrent ainsi inadaptées pour une application industrielle à faible coût. Dans cette thèse, nous avons d'abord réalisé un détecteur d'objets à corrélation sans avoir recours à la mesure du temps de vol. Pour améliorer les performances de la détection d'objet, nous avons proposé une nouvelle architecture combinant à la fois un radar CW Duplex monostatique avec une modulation BPSK. Nous avons développé une méthode de calibrage numérique pour corriger les défauts de ce type d'architecture. Finalement, nous avons étudié le problème de la détection d'objet en zone proche de l'antenne
The detection of static or mobile objects is widely used in industrial environments for control applications in the field of process automation. Several technologies (inductive, photoelectric, ultrasounds, etc. ) share the market of detection of objects. These technologies are limited in their applicability due mainly to their physical principles. On the other hand, the high frequency domain and particularly the Radar technology offer good performances in hostile environments. The objective of this thesis is to investigate ail the technical solutions brought by the Radar technology to design a detector of static or mobile objects satisfying the constraints of the industrial environment. Efforts in Radar technologies are often dedicated to the detection of mobile objects. Some of these technologies are capable of detecting static objects but with a resolution demanding a large frequency band-width. Thus, these technologies are incompatible with a low-cost industrial application. Ln this thesis we have realized a detector of objects using correlation which does not make use of the measure of the time of flight. To improve the performances of the detection of object, we have proposed a new architecture combining both a monostatic Duplex CW radar and BPSK modulation. We have developed a method of digital calibration to correct the defects of this type of architecture. Finally, we have studied the problem of the detection of objects in the close area of antenna

Abstract:
Les formats de modulation avancés, codant l'information sur la phase, la polarisation ou plusieurs niveaux d'amplitude de la lumière reçoivent aujourd'hui un intérêt croissant. En effet, ceux-ci permettent d'atteindre une meilleure efficacité spectrale et par conséquent des débits plus élevés. Ces caractéristiques sont actuellement très recherchées dans les télécommunications pour répondre à la demande constante d'augmentation de capacité des transmissions optiques fibrées. L'essentiel du travail effectué porte sur la génération de tels signaux dans des sources photoniques monolithiques sur InP faisant appel à un concept nouveau de commutation de phases optiques préfixées avec des modulateurs électro-absorbants. Une comparaison de notre technologie intégrée avec la technologie actuelle de génération de formats de modulation avancés démontre des possibilités nouvelles de réduction de taille, de diminution de consommation énergétique et d'évolution en vitesse de modulation jusqu'à 56 GBauds. Suite à la validation, par simulations, d'architectures de transmetteurs spécifiques pour la génération de formats de modulation avancés, nous réalisons en salle blanche les circuits photoniques intégrés d'étude. Les caractérisations statiques confirment le fonctionnement de toutes les fonctions intégrées des circuits et soulignent l'efficacité de la filière technologique. Pour une première démonstration de fonctionnalité nous choisissons un transmetteur BPSK capable de générer une modulation de phase à 12,4 GB. Ce résultat démontre la plus petite source intégrée BPSK à l'heure actuelle. Un autre circuit capable de générer des formats de modulation plus complexes est aussi caractérisé

This thesis investigates the design and implementation of turbo codes over the GNU radio. The turbo codes is a class of iterative channel codes which demonstrates strong capability for error correction. A software defined radio (SDR) is a communication system which can implement different modulation schemes and tune to any frequency band by means of software that can control the programmable hardware. SDR utilizes the general purpose computer to perform certain signal processing techniques. We implement a turbo coding system using the Universal Software Radio Peripheral (USRP), a widely used SDR platform from Ettus.

Abstract:
This chapter is devoted to the modeling of aircraft data transmission via low-orbit satellites. Satellite communication channel models were designed, which allow to investigate BER dependencies on the type of signal modulation, information transfer rate, signal power, antenna diameters, and nonlinearity of a high power amplifier. Impact of a modulation type (BPSK, QPSK, 8PSK, 16QAM), Eb / N0, satellite transponder amplifier gain without and with coding on a BER was investigated. Effectiveness of error detection and correction was analyzed using classic linear block and convolutional codes. Free space path loss, AWGN, and radio frequency satellite channels were considered. MIMO 2 × 1 and 3 × 2 fading uplink/downlink channels with antenna diversity were analyzed. Results were compared with AWGN uplink/downlink channels. On the base of these models, channels integrity was investigated.

"Parameters Estimation of Aircraft and RPAS Satellite Channels Based on IEEE 802.11a Standard." In Recent Advances in Satellite Aeronautical Communications Modeling, 65–132. IGI Global, 2019. http://dx.doi.org/10.4018/978-1-5225-8214-4.ch002.

Abstract:
This chapter deals with parameters estimation of satellite channels based on IEEE 802.11a standard. Dependencies of a signal to noise ratio on free space path loss for different types of modulation (BPSK, QPSK, 16QAM, 64QAM), noise temperatures, number of OFDM symbols, Doppler frequency offsets, satellite amplifier gain, and aircraft antenna diameter were received using model “OFDM_FSPL_Sat_FSPL_802.11a.” A method for parameters estimation of satellite OFDM communication channel was proposed. The spectrums and signals constellations of received signals were compared for different types of the amplifier nonlinearity. The developed model allows predicting spectral regrowth of digitally modulated OFDM signals due to the amplifier nonlinearity. Channel parameters were received for the Rayleigh and Rician fading, different types of Doppler spectrum, the gain of multipath channels, the delay time of message flow using models “OFDM_Multipath_Sat_Multipath_802.11a,” “OFDM_AWGN_Sat_Multipath_802.11a,” and “OFDM_FSPL_Sat_Rician_802.11a.”
