| 摘 要： | 分集接收技术在现代移动通信系统中,主要用以对抗由于快衰落引起的接收信号的快速变化,但同时也可以减轻由于阴影效应引起的慢衰落。瑞利信道分集接收的技术是针对在瑞利衰落环境下BPSK信号的ABER(平均误比特率),通过计算机仿真比较了a-SDC,r-SDC,aw-SDC,ar-SDC,MRC以及a-GSC等分集技术,可以看出某些选择合并技术在性能和复杂度方面明显优于其他分集技术。

| Abstract: | Diversity receiving technique is in great demand in modern mobile communication systems. So it is of great value to have a future research on it. Now many diversity receiving techniques in Rayleigh fading channel have been proposed. In this paper, we describe several diversity combining techniques about ABER of BPSK signal in Rayleigh fading channels and by the computer simulation the performance of a-SDC, r-SDC, ar-SDC, aw-SDC, MRC and a-GSC has been compared. From the analysis, we find that some selective diversity combinations are clearly better than others in performance and complications. |
