Abstract

Abstract:

In this paper, we investigate the outage performance of a dual-hop amplify-and-forward (AF) multiple-input multiple-output (MIMO) relay network, considering beamforming transmission with outdated channel state information (CSI) and an arbitrary number of co-channel interferers at both the relay and the destination. The exact closed-form expression for the outage probability is derived, and the asymptotic behavior of the outage probability is also presented to provide further insights into the system performance. Our results show that the system suffers a diversity gain loss caused by the outdated CSI, and the interference only degrade the coding gain of the system. Moreover, increasing antennas can achieve more performance gains, however, the gains decrease as the delay of the CSI increases.

Key words: outage performance|amplify-and-forward (AF)|beamforming|channel state information (CSI)
