BER-optimized power allocation for amplify-and-forward in single relay system
In single relay non-cooperative amplify-and-forward (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.
