摘　　要：结合能量收集技术,研究了放大转发双向中继网络的系统性能。基于双向中继系统中的两个端到端信噪比平衡准则,推导出了单中继选择情况下信源最优的功率分配方案和中继最优的能量收集比例。仿真结果证明所提方法能够实现最好的系统性能。通过比较发现,能量收集双向中继网络比传统双向中继网络能够实现更高的传输速率。The performance of amplify-and-forward based two-way relay network is analyzed in combina-tion with energy harvesting technology. According to the end-to-end signal-to-noise ratio（SNR） balancing criterion,the optimal power allocation of two sources and the optimal energy harvesting proportion of the single selected relay are derived. Simulation results show that the proposed method can achieve the best performance. Comparison shows that energy harvesting two-way relay communication network has a higher achievable transmission rate than conventional two-way relay network.
