A NEW COOPERATIVE TECHNIQUE FOR WIRELESS COMMUNICATIONS WITH IMPROVED DIVERSITY-MULTIPLEXING TRADEOFF

By Christos G. Tsinos and Kostas Berberidis

Abstract

In this work we present a new diversity-multiplexing scheme for the uplink transmission of a cooperative system consisting of single-antenna source and relay nodes and a multiantenna destination node. The proposed technique is based on the singular value decomposition of the channel matrix and, for the same rate, it exhibits higher diversity gain as compared to the existing schemes. Moreover compared with these techniques it is highly reconfigurable and has a lower complexity receiver structure. We evaluate the performance of the new technique via theoretical analysis and simulations. 1
