双中继协作通信的功率分配改进方案
Power Allocation for Two Relays Cooperative Communication
摘要
Abstract
To overcome the difficulty of single relay cooperative communication in deep fading channels and reduce the complexity of destination signal processing for multi-relay cooperative communication, power allo-cation scheme for two relays cooperative communication is proposed. Amplify-and-forward(AF) strategy, decode-and-forward( DF) strategy and hybrid decode-amplify-and-forward( HDAF) strategy for two relays are investigated, respectively. Under certain outage probability and power constraint, minimum powers for nodes are obtained through the Fmincon function embedded in MATLAB. Numerical results show that, in the same condition, as compared with AF and DF, the proposed two-relay HDAF strategy can save total power up to 4~9 dBm and 0. 5~1 dBm respectively,and minimize the total power consumption.关键词
