摘要 为了提高双向中继系统总速率,针对双向放大转发中继系统提出了一种运用信噪比平衡技术进行各节点间功率分配的最优功率分配方案,并推导得出了最优功率分配方案表达式。理论分析和仿真结果表明,所提出的最优功率分配方案有效提高了系统可达总速率,改善了系统性能。 In order to improve the sum-rate of the two-way relay system, this paper proposes an optimal power allocation scheme in Two-way AF relay system which uses the technology of SNR Balancing （SNR-Balancing-IPA） , and the expression of the optimal power allocation is derived. The theoretical analysis and simulation results show that the proposed Optimal Power Allocation scheme can effectively improve the sum rate of the system, thus improving the performance of the system.
