Performance Analysis of Multi-hop Macro-diversity in Rayleigh-Lognormal Composite Fading
瑞利-对数正态联合衰落下多跳宏分集的性能分析

Based on the concept of multi-hop transmission, a multi-hop macro-diversity is presented. In pure lognormal and Rayleigh-lognormal composite fading channels, a hexagonal macro-diversity cellular system is investigated. The Maximum Ratio Combing (MRC) is considered for the uplink analysis of the Bit Error Rate (BER) for DPSK. Numerical results show that the performance of the new system outperforms that of the conventional single-hop macro-diversity system. The multi-hop relaying can enhance the robustness of system performance to the different location of one mobile station, and it is benefit to reliable communication of the radio link.
