| 摘 要： | 本文提出一种基于多项式预测的判决反馈差分检测(PP—DFDD)来改善平坦Rayleigh衰落信道中Turbo乘积编码多元DPSK系统(TPC—MDPSK)性能的新方法。相对于传统的判决反馈差分解调而言，该新方法无需任何先验的信道信息，而且计算量较小。数值仿真结果表明该新方法可以改善衰落信道中TPC—MDPSK系统的错误平底。

| Abstract: | A novel decision feedback differential detection based on the polynomial prediction (PP-DFDD) to improve the performance of Turbo product coded M-ary DPSK (TPC-MDPSK) in flat Rayleigh-fading channels is proposed. The PP-DFDD does not need any channel state information and complexity is reduced significantly in comparison with conventional decision feedback differential detection (DFDD). Simulation results confirm that the error floor of TPC-MDPSK in flat Rayleigh-fading channels can be reduced by means of PP-DFDD. |
