摘要
移动通信中的天线微分集技术能有效地改善由于电波多径传播所造成的衰落的影响。而最大比例合成技术(MRC)是最有效的分集信号的合并技术,能最大限度地提高接收信号的信噪比。本文通过对MRC算法性能的分析、及比较在MRC分集接收系统中分集距离d、系统误码率BER与信噪比SNR之间的关系来得出如何获得最佳的MRC分集合并效果的结论。
The Antenna Micro-diversity techniques in mobile communication can effectively improve the radio wave propagation caused by multipath fading effects. The Maximum ratio combining (MRC) is the most effective signal diversity combining technique, to maximize the received signal to noise ratio. Based on the analysis of MRC algorithm performance, and the analysis of the correlation among the diversity distance d, the BER and SNR in MRC diversity reception system, the conclusion to get the best results for diversity combination results is derived.
