Abstract:
The use of the continuous phase modulation (CPM) is interesting when the channel represents a strong non-linearity and in the case of limited spectral support; particularly for the uplink, where the satellite holds an amplifier per carrier, and for downlinks where the terminal equipment works very close to the saturation region. Numerous studies have been conducted on this issue but the proposed solutions use iterative CPM demodulation/decoding concatenated with convolutional or block error correcting codes. The use of LDPC codes has not yet been introduced. Particularly, no works, to our know

The combination of Space-Time (ST) coding and Continuous-Phase Modulation (CPM) produces a low power, energy efficient communication scheme suitable for wireless transmission.

Abstract:
The use of coded modulations such as continuous phase modulation (CPM) can improve the power and bandwidth efficiency of digital communication links. The price paid for these gains is in increased receiver complexity. The power efficiency attainable with the highly redundant signal sets employed by coded modulations becomes limited by the ability of the receiver to achieve accurate carrier phase synchronisation. Power efficiency is assessed in terms of the bit error rate performance in white Gaussian noise. A new CPM detector called the partially coherent Viterbi algorithm (PCVA) is introduced

Continuous phase modulation~(CPM) is a non-linear, constant-envelope modulation scheme with memory, known for its bandwidth and power efficiency. Multi-h CPM uses multiple modulation indices in successive symbol intervals to improve the error performance as compared to single-h CPM~(basic CPM that utilizes only a single modulation index). One of the major applications of multi-h CPM is in aeronautical telemetry systems. Modern aeronautical devices host an increasing number of sensors, which can transmit flight testing data to the ground station. However, this excess data transfer increases the

In this thesis, we introduce the concept of L2-orthogonality for non-linear Space-Time codes (STC). Our approach generalizes code design based on pointwise orthogonality.

Abstract:
In this thesis, noncoherent differential demodulation of CPM signals with joint carrier frequency offset and symbol timing estimation is investigated. CPM is very attractive for wireless communications owing to major properties: good spectral efficiency and a constant envelope property. In order to demodulate the received CPM signal differentially, the symbol timing and the carrier frequency offset have to be estimated accurately. There are numerous methods developed for the purpose. However, we have not encountered studies (which are based on autocorrelation estimation and hence suitable for

Abstract:
Recently, a study on obtaining better Euclidean distance for CPM (Continuous Phase Modulation) signals that fit well-known GSM spectral envelope has been carried out, and significant performance improvements were obtained. Two new pulse shapes, which are represented using 8th degree polynomials, were optimized to give the best error performance under the constraint that the PSD stays below GSM spectral standards. However, the approach uses parameters that cause the number of states to increase considerably, and thus yielding high complexity for receiver implementation. In this thesis, a study

These are key conditions for evaluating the usefulness of a convolutional code. One of the most effective and industry-standard method is to use Punctured Convolutional Codes technology. The principle is to periodically cut off some of the transmitted bit so that the coding rate changes but the receiver is simplified. In t

Since CPM signals have been extensively discussed in the field ofcommunications, due to CPM signals have properties of phase continuity, constant envelope, narrow frequency spectrum and a fast roll-off side-lobe. To keep phase continuity in the transmitted signals, CPM has memory inherently and the modulators are deployed with Viterbi algorithm to achieve coding gains.

Abstract:
碩士<br>國立高雄第一科技大學<br>電腦與通訊工程所<br>91<br>Continuous phase modulation (CPM) is a modulation with memory. The memory results from the continuity of the transmitted carrier phase from one signal interval to the next. For specific forms of phase function and modulation indices, CPM can be represented with various type of modulations, namely, minimum shift keying (MSK), continuous phase frequency shift keying (CPFSK) and etc. Because of a single carrier whose phase is changed continuously, can avoid the use of signals having large spectral side lobes, CPM are thus attentive in mobile communications.

Abstract:
The continuous phase modulation (CPM) has a constant envelope and compact output power spectrum that makes it a promising underlying technology for power and spectrum efficient broadband wireless communications. However, high implementation complexity (especially the complexity of the receiver) required to deal with the phase memory and inter-symbol interference has impeded its adoption for broadband wireless communications, and only a few simple CPM modulation schemes have mainly been used, e.g. binary MSK and GMSK. Thus, research on efficient CPM transceivers to reduce the computational and
