Abstract

In this paper, we study the performance of a wireless communication system, where an arbitrary number of amplifyand- forward relays cooperate to enhance the signal between source and destination. The source and destination are hidden from each other, and there is no direct link between them. Optimal relay power control (ORPC) is introduced as an effective scheme to achieve cooperative diversity. This paper develops a new and more accurate model for the ORPC scheme in multiple antenna relays scenario, and takes into account the effects of
fading and thermal noise at both the relays and destination. This leads to the derivation of new analytical expressions for the overall spectral efficiency which can be used to estimate the throughput, and to study the impact of different system parameters on efficiency. The accuracy of the new mathematical
results is confirmed by Monte Carlo simulation. Index Terms—amplify-and-forward, moment generating function, multiple input multiple output, Optimal Relay Power Control, spectral efficiency, relay.
