BER-OPTIMIZED POWER ALLOCATION FOR AMPLIFY-AND-FORWARD IN SINGLE RELAY SYSTEM

摘要：

In single relay non-cooperative amplify-andforward (AaF) system, taking into account both long-term path loss and short-term Rayleigh fading, a closed form expression to distribute total power optimally among source and relay is obtained, which minimize end-to-end BER. The simulation results under various channel conditions and scenarios show that it is consistent with theoretical analysis, and optimal power allocation is realized to minimize BER in a simple way.
