Performance Analysis of MMRT in Rayleigh Fading Channels
-
摘要: 为了提高系统性能减少系统功耗和硬件复杂度等，该文提出一种在基站采用最少选择最大比发射的发送分集技术，即MMRT。利用随机矩阵和排序统计的理论知识，该文对MMRT技术进行了详细的性能分析。并得到其在瑞利衰落信道下的中断概率、误码率等的确切表达式。最后通过仿真试验验证了理论分析的正确性。Abstract: In order to improve the system performance and reduce hardware complexity further, a new transmit diversity scheme, Minimum-selection Maximum Ratio Transmit (MMRT) scheme is proposed. Based on the theory on random matrix and order statistics, an exact analysis for MMRT is carried out. The closed-form outage probability and the Bit Error Rate (BER) of the MMRT system, for Rayleigh fading scenario, are presented. The analytical results are verified by simulation.
