This paper studies the performance of MIMO multichannel beamforming systems in the presence of unequal-power co-channel interference and noise. The authors present exact expressions for the symbol error rate, and investigate the high signal to noise ratio regime by deriving explicit closed-form expressions for the diversity order and array gain. Their results are based on new exact and asymptotic marginal ordered eigenvalue distributions which they derive for a certain class of finite-dimensional complex random matrices. Multiple-Input Multiple-Output (MIMO) communication systems have received considerable attention in recent years as a means of achieving significantly increased capacity and performance.
