Abstract :
Multi-input multi-output (MIMO) is a 4G Wireless Communication Technique and is supposedly has the most promising reign. Multi-user MIMO has an edge over 4G wireless systems due to their better spectral efficiency, diversity gain and interference suppression. This paper incorporates the moment generating function (MGF) based closed form upper bounds of pair wise error probability (PEP), which are derived for MU-MIMO systems. These upper bounds are then extended for different equalizers like, zero forcing (ZF), minimum mean square error (MMSE) and maximum likelihood (ML). BER expressions are also derived for MU-MIMO system under independent and spatially correlated quasi-static Rayleigh fading channels. Simulation results for upper bounds are drawn and similar performance with the analytical results have been subsume in this paper.
