Iterative transceiver design for MIMO AF relay networks with multiple sources

Abstract

This paper addresses the problem of transceiver design for an amplify-and-forward relay network with multiple sources, multiple relays and multiple destinations. Each node in the network is assumed to be equipped with multiple antennas. A general iterative algorithm is proposed based on convex quadratic optimization theory to minimize mean-square-error of the recovered signals at the destinations. Its convergence and extensions to other scenarios are also discussed. Finally, the effectiveness of the proposed iterative algorithm is demonstrated by computer simulations. ©2010 IEEE.published_or_final_versionThe IEEE Military Communications Conference (MILCOM 2010), San Jose, CA., 31 October-3 November 2010.
