摘　　要：针对源端到目的端距离较远的场景对多跳解码转发无线网络进行研究,推导出高信噪比条件下的中断概率近似表达式,并提出一种通过功率优化来最小化无线网络中断概率的解决方案﹒仿真实验的结果表明,在多跳分集无线网络中采取功率优化方案致使网络的中断性能明显优于等功率分配方案﹒Aiming at the long distance scene from source to destination node this paper analyzes the multi hop wireless network of decoding and forwarding. An approximate formulation of the outage probability has been derived in high signal-to-noise ratio and an optimum power allocation is proposed to minimize outage probability by optimizing the power. The simulation results show that the optimum power allocation outperforms the equal power allocation in multi-hop diversity wireless network.
