Executive Summary

This paper presents simulation results and comparative analysis of some Spatial Multiplexing Techniques for Multiple-Input Multiple-Output (MIMO) based Wireless Communication Systems. Performance of various detection schemes are evaluated through MATLAB simulation study. The Bit Error rate and complexity of these schemes is discussed. The simulation is carried out for different modulation schemes. Comparative study shows Maximum Likelihood detection scheme results into best performance. But its computational complexity is very high. Hence there is a need to find less complex techniques which can provide quasi-ML performance.
