Abstract

This paper presents a joint relay selection and power allocation scheme for amplify-and-forward two-path relaying networks, in which different relay nodes forward information symbols alternatively in adjacent time slots. Our approach is based on the maximization of the received signal-to-noise ratio under total power consumption by the transmission of the symbol. We show that in spite of inter-relay interferences, the maximization problem has a closed-form solution. Simulation results explicitly indicate that the performance of proposed approach outmatches the existing methods including equal power allocation and one-path relaying.
