研究了N-Nakagami衰落信道下基于多中继的增量式混合译码-放大-转发(IHDAF)中继移动到移动(M2M)网络的发送天线选择(TAS)中断概率(OP)性能。推导了最优和次优TAS方案的近似最小二乘解的闭合表达式。以性能优化为目标，建立了功率分配问题。然后通过数值仿真对不同条件下的OP性能进行了评估，以验证分析的正确性。仿真结果表明，最优TAS方案比次优TAS方案具有更好的运算性能，功率分配参数对运算性能有重要影响。
The outage probability (OP) performance of multiple-relay-based incremental hybrid decode-amplify-forward (IHDAF) relaying mobile-to-mobile (M2M) networks with transmit antenna selection (TAS) over N-Nakagami fading channels is investigated in this paper. The closed-form expressions for approximate OP of the optimal and suboptimal TAS schemes are derived. The power allocation problem is formulated for performance optimization. Then the OP performance under different conditions is evaluated through numerical simulations to verify the analysis. The simulation results showed that optimal TAS scheme has a better OP performance than suboptimal TAS scheme; the power-allocation parameter has an important influence on the OP performance.
