摘要

研究了具有连续相位调制(TCCPM)的交错网格编码系统。结果表明，栅格码、交织器和CPM调制器的组合可以显著增强传输信号的距离频谱。通过考虑栅格码、交织器和CPM调制器作为串行连接码的组合，推导出误码率的上界。最后，提出了迭代相干和非相干接收机，并通过计算机仿真对其性能进行了评价。

Iterative demodulation and decoding of trellis coded CPM

Interleaved trellis coded systems with continuous phase modulation (TCCPM) are considered. It is shown that the combination of a trellis code, interleaver and the CPM modulator results in a significantly enhanced distance spectrum for the transmitted signals. Upper bounds on the bit error rate are derived by considering the combination of the trellis code, interleaver and the CPM modulator as serially concatenated code. Finally, iterative coherent and non-coherent receivers are proposed and their performance is evaluated through computer simulations.
