摘　　要：文章主要在Nakagami-m信道环境下研究了基于增量中继的机会选择的中断概率和吞吐量性能。在各个信道为独立非同分布条件下,推出了基于增量中继的放大转发机会选择的中断概率和吞吐量的近似表达式。通过仿真验证了中断理论值是一个下界,同时通过仿真发现基于增量中继的放大转发机会选择机会比传统的放大转发机会选择的吞吐量要高。Outage probability and throughput over Nakagami-m of incremental relaying using opportunistic with amplify and forward were investigated. Closed-form expressions for the outage probability and throughput were also derived under the mode of Maximal Ratio Combining （MRC） and Selection Combining （SC） including direct link at arbitrary SNR （Signal to Noise Ratio） regime. Computer simulation verifies the analysis. The incremental relaying using opportunistic and opportunistic without incremental relaying was compared. Simulation shows that the outage probability and spectral efficiency of the incremental relaying using opportunistic outperforms the opportunistic relaying.
