摘要
分集是数字通信中最有效的抗多径裹落技术,在无线通信中采用分集技术可以改善系统的差错性能。本文详细分析了空间分集中性能最佳的最大比合并方式(MRC)的差错性能,并通过计算机仿真,给出了误码曲线。最后本文还给出了一种可行的最大分集合并的具体算法和仿真结果。
Diversity is the most effectively anti-multipath-fading technique in the digital communication and the ad- vantage of diversity is obtained in the wireless communication. Firstly, the performance of the Makimal Ratio Com- bining which is the best kind of Space Diversity is analysed. Secondly, the computer simulation results are provided. Finally, a practical algorithm and its simulation results are proposed.
