2 M态 TCM8PSK 设计及在超短波通信系统的应用

摘要

The optimal convoluted code machine and state-transfer matrix base on 32-state and 64-state TCM8PSK are introduced .The bit error rate and complexity property among 4-state ,8-state ,16-state TCM8PSK are analyzed .Simulation results show that 8-state TCM8PSK is suitable for giving more coding gain and less complexity in certain VHF wireless com -munications system .The application of 8-state TCM8PSK is introduced in physicschannel of VHF communications system .%介绍了32态、64态的 TCM8PSK 网格编码调制的最优卷积编码器和状态转移矩阵，并对4态、8态和16态TCM8PSK 的误码率性能及实现复杂度进行分析对比，仿真结果表明，采用8态的 TCM8PSK 更能满足某超短波通信系统设计需求，并给出8态 TCM8PSK 在该系统物理信道的应用。
