“…Currently, 16-QAM technique is being used in the forward link of the 3G (third generation) cellular dataonly system (IS856) and being widely investigated (e.g., see References [6,7]) in satellite domains. In Reference [8], the effect of nonlinear distortion on the error performance of 16-QAM rectangular signaling scheme, operating in a typical satellite channel, was investigated by means of computer simulation. In Reference [9], Craig provided a simple formulation technique for evaluating the SER of two dimensional signals in the linear additive white Gaussian noise (AWGN) channel, which was applied and extended later by many researchers for SER evaluation.…”

This paper presents a simplified mathematical approach to evaluate the performance of any given circular constellation of 16-level quadrature amplitude modulation (16-QAM) in terms of symbol error rate (SER). Following this approach, with the aim to work with memoryless nonlinear satellite channels, a model is derived as a generalized form for both linear and nonlinear channels in the presence of down link additive white Gaussian noise (AWGN). The analysis provides means to calculate the optimal ring ratio (RR) and phase difference (PD) for several possible candidates of 16-QAM circular constellations. The effects of RR and PD on the SER performance are investigated in the analysis. To overcome the nonlinear distortion, data pre-distortion is taken into account in the study. The paper gives a general procedure for data pre-distortion implementation for all circular 16-QAM constellations. The analytical formulation has been extended for total degradation (TD) performance measure as a function of input back-off (IBO) of the nonlinear amplifier. A SER performance-comparison between different constellations for 16-QAM systems has also been presented in this paper. The analytical results are validated by simulation.

This paper proposes efficient multidimensional coded modulation techniques which can be used for digital communications over nonlinear channels. An 8D-CEMS (8 Dimensional Constant Envelope Modulation Scheme) with constant envelope of the modulated signal is introduced. Computer simulation results show that this modulation scheme lead to significant performance improvement on non-linearly amplified channel as required in most commercial satellite and terrestrial microwave systems. The biterror rate of Pk = at Eb/No = 8.5 dB at spectral efficiency 3 bits/s/Hz is obtained.

There is interest in getting high bit rate over satellite channel containing a nonlinear power amplifier. This paper studies different orders of amplitude phase shift keying (APK) modulation, 16-ary quadrature amplitude modulation (QAM) and predistortion considerations over the satellite power amplifier. Satellite transmission channel has been modelled to simulate and compare between methods for a better performance. The Saleh Model and Ghobni model has been selected from literature measurements of the travelling-wave tube-amplifier (TWTA) and solid state-power-amplifier (SSPA) respectively; however, in the simulation the TWTA gives better performance than SSPA in most modulation techniques. It was investigated with preditortion and without predistortion the best modulation constellation performance under nonlinear communication channel.Index Terms-Amplitude phase-shift keying (APK) modulation, nonlinear channel, and digital satellite communication.
