Abstract

The outage probability (OP) performance of multiple-relay incremental-selective decode-and-forward (ISDF) relaying mobile-to-mobile (M2M) sensor networks with transmit antenna selection (TAS) over N-Nakagami fading channels is investigated. Exact closed-form OP expressions for both optimal and suboptimal TAS schemes are derived. The power allocation problem is formulated to determine the optimal division of transmit power between the broadcast and relay phases. The OP performance under different conditions is evaluated via numerical simulation to verify the analysis. These results show that the optimal TAS scheme has better OP performance than the suboptimal scheme. Further, the power allocation parameter has a significant influence on the OP performance.

摘要

研究了在N- Nakagami衰落信道上具有发射天线选择（TAS）的多中继增量选择解码转发（ISDF）中继移动对移动（M2M）传感器网络的中断概率（OP）性能。推导了最优和次优TAS方案的精确闭式OP表达式。制定了功率分配问题，以确定广播和中继阶段之间发射功率的最佳分配。通过数值模拟评估不同条件下的OP性能，以验证分析结果。这些结果表明，最优TAS方案比次优方案具有更好的OP性能。此外，功率分配参数对OP性能有显著影响。
