摘要 针对放大转发(AF)协同分集网络在独立同分布(i.i.d.)平坦Nakagami-m衰落信道上的增量中继进行了端到端性能分析,给出了误码率(BER)的最小下界解析解以及信噪比(SNR)的中断概率。数值模拟显示分析结果与仿真结果完全匹配,同时,还针对不同信噪比检测门限条件下的系统误码率和中断概率的性能进行了评估和比较。 Compared with the regular cooperative diversity networks, incremental relaying cooperative diversity makes more efficient use of the channel resources. In this paper, the end-to-end performance of incremental relaying for amplify-and-forward （AF） cooperative diversity networks over independent and identical distributed （ i. i. d. ） fiat Nakagami-m fading channels is analyzed. Tight lower bounds closed-form expressions for the bit error rate （BER） and the signal-to-noise ratio （SNR） outage probability are given. Numerical investigation shows that the analytic re- sult makes an exact match with the simulation, and system performances in different cases are evaluated and com- pared.
