摘要

协作分集在新兴的无线通信系统中得到了广泛的应用。本文分析了CO-MRC接收机在广义统计测量衰落信道下的平均误差率性能。多样性联系被认为是独立的，但不一定是完全消失的。在不同的平均信噪比(γo)下，对一般CO-MRC信噪比进行了仿真。然后，利用SNR-PDF表达式推导出不同相干调制技术下的近似平均误差率的封闭表达式。给出了蒙特卡罗仿真结果来验证信噪比pdf和推导的平均错误率表达式。

Error rate performance analysis of cooperative MRC receivers over generalized fading channels

Cooperative diversity is widely used in the new emerging wireless communication systems. In this paper, the average error rate performance of Cooperative Maximum Ratio Combing (CO-MRC) receiver is analyzed over generalized statistically-measured fading channels. The diversity links are assumed to be independent but not necessarily identically-faded. The general CO-MRC SNR-PDF is simulated for different values of the average Signal-to-Noise Ratio (γo). Then, the SNR-PDF expression is utilized to derive a closed-form expression for the approximated average error rate using different coherent modulation techniques. Monte Carlo simulation results are presented to validate the SNR-PDFs and the derived average error rate expressions.
