Abstract:

AbstractIn the age of digital media, delivering broadcast content to customers at an acceptable level of quality is one of the most challenging tasks. The most important factor is the efficient use of available resources, including bandwidth. An appropriate way of managing the digital multiplex is essential for both the economic and technical issues. In this paper we describe transmission quality measurements in the DAB+ broadcast system. We provide a methodology for analysing parameters and factors related with the efficiency and reliability of a digital radio link. We describe a laboratory stand that can be used for transmission quality assessment on a regional and national level.

The system consists of four components: sensor and modulation circuit part, A/D transformation and send part, optical fiber coupling part and the receiver display part. The system has the following characteristics: The encoder is used to encode and send the digital signal of the measured parameters. Through the optical fiber coupling, this system displays the corresponding measurement parameters after decoding by the decoder. System circuit design is simple, easy debugging, reliable of information transmission, high precision of data transmission, particularly good anti-interference, no need of great sending power. It can be applied to a strong electric field or strong magnetic interference occasions at a distance from tens of meters to hundreds of meters.

Abstract:

The paper is about the transmission, compression, detection of the video based on simulation for the various communication applications. The video and image compression overcomes the problem of reducing the amount of data required to the information that has to be transmitted and this saves the bandwidth required for transmission of data and memory which is required for storage purpose. Hence video compression reduces the volume of the video data with a small change in quality of the video. Compressed video transmission can be done over a channel by huffman coding for the source at transmitter side and then channel codes is done by technique called hamming. The data which is to be sent through channel is a BPSK modulated so the received data is demodulated followed by the channel decoding, source decoding using inverse of the techniques used in the transmitter side to obtain the original transmitted video. The above procedure is done for the input video taken by camera and this compressed video can be transmitted then detected at receiver by digital communication system(DCS) which is simulated in the MATLAB.

Abstract:

With the development of the Internet, how to provide a high-speed and high-security comprehensive network has become urgent issue. In this project, we propose hybrid analog/digital transmissions format scheme which integrated optical code-division multiple-access (OCDMA) and polarization multiplexing technique in free space optics (FSO) transmission. Orthogonal frequency division multiplexing (OFDM) transmits as the analog format and (on-off keying) OOK transmits as digital format in the study, respectively. In the proposed hybrid OCDMA system, it has high-speed transmission, signal security and low cost...etc. we adopt quasi-orthogonal Walsh-Hadamard codes (WHC) that with fixed cross correlation value as the codeword for each base station. With the property, the multiple access interference (MAI) can be efficiently eliminated by using the balanced detection scheme at the receive end. The constellation and eye diagrams show that both OFDM signal as analog signal and OOK modulation as digital signal in the proposed hybrid OCDMA system perform good performance in FSO transmission.

Abstract:

Purpose of this research wants to use a device, called Dante board, the board enabled AD converter. It digitalizes audio and transmits the audio using TCP/IP technology through cat5 cable to replace the expensive analog cable used in the past. Still, there are some problems needed to be overcome. First of all, during the analog-to-digital process, distorted audio issues are often encountered due to inconsistency of the encoder during digital sampling. In order to compensate the distortion during the conversion, frequency needs to be filtered out to compensate or attenuate. Secondly, due to delay in Internet transmission, the audio outputs by each device may not be synchronized. Therefore, each device needs to have its own clock to overcome the delay and reach the synchronized effect through clock synchronization. Also, the IEEE1588 precision time protocol (PTP) is used in clock synchronization to synchronize the audio in each device.
