提出了一种组合编码和网格形调制方案，以减少带限 8-PSK 系统的包络波动，从而减轻传输路径中非线性引入的失真。网格整形方法用于影响传输信号的符号转换。因此，可以避免具有大相位差的转变导致带限调制信号的包络中的强烈波动。由于非线性失真而导致的频谱旁瓣的恢复大大减少。额外的编码导致误码率与传统 QPSK 相当。<<ETX>>
A combined coded and trellis shaped modulation scheme is proposed to reduce the envelope fluctuations of a bandlimited 8-PSK system and hence to mitigate distortions introduced by nonlinearities in the transmission path. The method of trellis shaping is used to influence the symbol transitions of the transmitted signal. Thus, transitions with large phase differences causing strong fluctuations in the envelope of the bandlimited modulated signal can be avoided. The restoration of the spectral sidelobes due to nonlinear distortion is considerably reduced. Additional coding leads to a bit error rate comparable to that of conventional QPSK.<<ETX>>
