双向中继系统的联合中继选择和功率分配策略
Joint Relay Selection and Power Allocation Strategy of Two-way Relay System
摘要
Abstract
In order to improve the sum-rate of two-way relay system,this paper proposes a joint relay selection and power allocation strategy based on in network coding two-way relay system model.A relay selection scheme of Maximized Minimum Channel Gain (MMCG) and Maximize Harmonic Average(MHA) is proposed.The optimal power allocation scheme between the sources and the relay in two-way relay system is proposed based on maximizing the sum rate of the system.Simulation results show that the proposed joint MMCG relay selection and the optimal allocation strategy can effectively improve 1.6 bit/s/Hz on the sum rate of system in two-way relay system with Physical-layer Network Coding(PNC) than joint BRS relay selection strategy.关键词
