| 摘 要： | 提出具有两路接收分集Turbo乘积编码引导符号辅助调制(TPC-PSAM）的16QAM系统的实现方法。该系统将Turbo乘积编码和分集接收用于改善16QAM系统在平坦衰落信道中的性能。通过对衰落信道中的数值仿真，结果表明具有接收分集的TPC-PSAM系统比TPC-PSAM系统明显的改善，同时可以减小接收机在不同衰落信道中的性能差异。

| Abstract: | This paper presents the turbo product coded pilot symbol assisted modulation (TPC-PSAM) system with two-branch receive diversity. The turbo product coding and receive diversity are used to improve the performance of 16QAM system in flat-fading channel. The numerical simulation shows that receive diversity can improve the performance of TPC-PSAM and reduce the performance difference in the different fading channels. |
