摘　　要：本文结合连续相位调制的分解,对串行级联连续相位调制系统的联合迭代解调解码进行了研究。连续相位调制的分解包括一个连续相位编码器和一个无记忆调制器,它和外部卷积码通过交织器相连形成Turbo码的串行级联结构。应用SOVA算法,本文给出了串行级联连续相位调制系统的联合解调解码的迭代算法,并进行了仿真分析。This article studys decoding combined with demodulation of SCCPM system using a decomposed cpm model.The de-composed CPM modulator comprising a continuous phase encoder and a memoryless modulator is implemented and concatenated with an outer convolutional encoder,such that it forms a system like Turbo code.A unified demodulation/decoder is given using SO-VA algrithm and also simulation result.
