Abstract

A dual-hop transmission in Rayleigh fading channels is presented where the relay uses Amplify and Forward (AF) protocol and Selection Combining (SC) technique. A closed-form expression is derived for outage probability of the overall received SNR at the destination. Also, the performance analysis is presented in terms of the Average Bit Error Rate (ABER) and expressions are derived for its upper and lower bounds. Finally, comparison between DF and AF systems are presented. We use simulation to verify the analytical results. Numerical results show that the proposed relaying system outperform the conventional relaying which use a single antenna in receiver and transmitter.
