In Nakagami-m channel, the outage probability and throughput of incremental relay ing using opportunistic are investigated. Using the mode of selection combining (SC), include ing direct link, the closed-form expressions for the outage probability and throughput is de rived at an arbitrary signal to noise ratio (SNR) regime, using the decode and forward method. Computational result verifies the analysis. The incremental relaying using opportunistic is com pared with the one using opportunistic without incremental relaying. Simulation result shows that the throughput of the incremental relaying using opportunistic outperforms the traditional opportunistic relaying.%研究了基于增量中继机会选择策略在Nakagami-m信道下的中断概率和吞吐量性能.在目的端采用选择性合并方式的条件下,理论分析得出了该策略在进行译码转发时的中断概率与吞吐量的闭合表达式,仿真结果与该理论值相一致.仿真结果还表明,基于增量中继的DF机会选择策略的吞吐量性能与传统机会选择策略的吞吐量性能相比有了较大的提升.
