Executive Summary

In this paper, the author analyze the performance of a cooperative spatial multiplexing scheme using amplify and forward relays over Rayleigh fading channels. The author proposes a simple user and relay selection scheme, and demonstrate that gains in spectral efficiencies are possible by such opportunistic selection. Using a bound on the outage performance, the author develops a power control mechanism. The author develops a bound on the ergodic rate of the proposed scheme. Computer simulation results are presented to demonstrate the performance of the scheme, and to validate the analytical expressions.
