Performance Enhancement of Multi-Input Multi-Output (MIMO) System with Diversity

MIMO is one of the techniques proposed to 3G and 4G LTE-A systems for its added benefits of higher data rates and low bit error rates. The gist of MIMO working is its ability to increase number of channels; thus increasing diversity gain. Correspondingly, more users are accommodated in one communication system. In this work, different MIMO schemes more specifically receive and transmit diversity are analyzed using MATLAB Simulations and the performance criteria are Bit Error Rates (BER), Cumulative Distribution Function (CDF) and channel capacity. MIMO has perfect results but it increases system complexity and this particular constraint limits its implementation to. More advanced system now days are a bit advanced 4 x 4 systems but this is the limit till now.
