中文摘要：
通过中继选择和功率分配,可以达到提高two-way中继系统总速率的目的。综合考虑中继节点处的接收信噪比和中继节点到目的节点间的信道增益,提出了two-way AF中继系统中的双向中继选择策略（BRS）;同时,在总功率受限的条件下,建立了two-way AF中继系统中的优化功率分配模型,通过对模型进行数学分析求解,提出了一种自适应的最优功率分配策略（OPA）。仿真结果证明两种策略均能提高系统总速率。
英文摘要：
This paper could achieve the purpose of improving the sum-rate of two-way relay system by relay selection and power allocation.Both considered the receive SNR（signal noise rate）at the relay node and the channel gain between relay node and destination node,proposed a BRS in two-way AF relay system.Also established the optimal power allocation mode in two-way AF relay system when total power was limited.And proposed a self-adaptive OPA scheme according to analyzing and solving the optimal mode.Simulation result shows that both the strategies can enhance the sum rate of the system.
