Abstract

Motivated from the recent works related to multi-antenna fixed relay network, this investigates the outage performance of a system in which source communicates with destination via two multi-antenna relays. A new protocol has been proposed for this scheme which outperforms the previous scheme published in [1]. A closed-form expression of outage probability and average transmitted power have been derived for more versatile Nakagami-m fading channel, with integer values of m. The effect of number of relay antennas, relay placement and swapping of relay assignment in various fading condition have also been studied.
