| 摘 要： | 由于无线衰落信道中差分检测Turbo乘积编码调制具有良好的性能,文中研究了相关平坦Rayleigh衰落信道中差分检测Turbo乘积编码MDPSK信号的等增益分集,这种等增益分集接收无需任何信道状态信息.研究结果表明,等增益合并可以改善快衰落信道中TPC-MDPSK的错误平底效应,等增益分集合并的Turbo乘积编码的MDPSK信号在相关系数为0.5的平坦Rayleigh衰落信道中的性能和独立衰落信道中的系统性能相差仅1 dB.

| Abstract: | The detection method and performance of equal gain combining turbo product coded MDPSK (TPC-MDPSK) in correlated Rayleigh-fading channels is studied. The equal gain combining TPC-MDPSK is realized without any channel state information. The results show that the EGC can reduce the error floor of TPC-MDPSK in rapid fading channels. The performance of TPC-MDPSK with EGC in the correlated channel with correlated coefficient of 0.5 is only 1dB worse than the performance in independent fading channel. |
