On the Uplink Performance of Cooperative Diversity with Multiple-Antenna Terminals

Abstract

There has been an increasing attention on cooperative diversity, which is a method to allow a single-antenna mobile to share other mobiles' antennas and thus achieve transmit diversity. The use of multiple-antennas, however, has been identified as a certain trend for high-rate transmissions over wireless channel. In this paper, we investigate the uplink performance of a single-relay cooperative scenario where the source, relay and destination terminals are all equipped with multiple-antennas. In our analysis and simulation, the relativity between different antennas at the same mobile terminal is taken into account to make our results more close to the actual cellular wireless communication system.
