“…The performance of the 16-QAM demodulator in the linear channel, including amplitude, timing and phase estimation subsystem degradations, is very close to the analytical upper bound in AWGN [28], [29]. For the 16-state code the coding gain of coded 16-QAM with respect to uncoded 8-PSK at P e = 10 −5 is about 4.4 dB.…”

Abstract-This paper investigates the performance of M -ary Amplitude-Phase Shift Keying (APSK) digital modulation over typical nonlinear satellite channels. The effect of the satellite nonlinearity is studied, and distortion pre-and post-compensation techniques for coded APSK are presented. Moreover, clock timing, signal amplitude and carrier phase recovery schemes are discussed. For the latter, a new class of non turbo decoder-aided closed-loop phase synchronizers featuring good performance and low complexity is studied. Finally, an end-to-end coded APSK system simulator inclusive of the satellite channel model and synchronization sub-systems is discussed and its performance compared to standard trellis-coded QAM concatenated with Reed-Solomon codes, showing a remarkable gain in both power and spectral efficiency. Coded APSK, recently selected for the new standard -DVB-S2-for digital video broadcasting and interactive broadband satellite services [1], is shown to represent a power-and spectral-efficient solution for satellite nonlinear channels.

“…Construction of optimal TCM codes is beyond the scope of this paper, and the related details can be found in [4]. From VLSI implementation perspective, a TCM encoder consists of four main parts: a differential encoder, a binary convolutional encoder, a multidimensional mapper and the 8PSK modulator, as shown in Fig.…”

“…TCM schemes using multi-dimensional constellations have been shown to further improve the error performance. In [4], a systematic approach to partitioning multi-dimensional signals is proposed. More recently, iterative Error Correction Codes (ECC) such as Turbo codes [5] and Low Density Parity-Check (LDPC) codes [6] have become popular due to their near-Shannon-limit decoding performance.…”

This paper presents a low-complexity, high-speed 4-dimensional 8-ary Phase Shift Keying Trellis Coded Modulation (4-D 8PSK TCM) decoder. In the design, an efficient architecture for the transition metrics unit (TMU) is proposed to significantly reduce the computation complexity without degrading the performance. In addition, pipelining and parallel processing techniques are exploited to increase the decoding throughput. Synthesis results show that the FPGA implementation of the TCM decoder can achieve a maximum throughput of 1.062 Gbps.

“…Since maximizing the SSED of the code is the design criterion of trellis codes over AWGN channels, then the set partitioning optimized for AWGN channels can be utilized. The set partitioning for multidimensional MPSK signal space for AWGN channels was presented in [16]. The same terminologies used for the first approach in defining set partitioning are used here.…”

This paper presents the design of 8PSK space-time (ST) trellis codes suitable for rapid fading channels. The proposed codes utilize the design criteria of ST codes over rapid fading channels. Two different approaches have been used. The first approach maximizes the symbol-wise Hamming distance (HD) between signals leaving from or entering to the same encoder's state. In the second approach, set partitioning based on maximizing the sum of squared Euclidean distances (SSED) between the ST signals is performed; then, the branch-wise HD is maximized. The proposed codes were simulated over independent and correlated Rayleigh fading channels. Coding gains up to 4 dB have been observed over other ST trellis codes of the same complexity.
