Multiple Input and Multiple Output (MIMO) is an indispensable key air-interface technology for implementing high data-rate wireless communications with limited frequency resources. In the present paper performance analysis for MIMO Orthogonal Frequency Division Modulation (OFDM) system with various detection schemes is reported. The performance of two detection techniques i.e Zero Forcing (ZF) and Minimum Mean Square Error (MMSE) is measured for various modulation schemes viz 4-QAM, 16-QAM, 64-QAM and 256-QAM. Extended vehicular environment with low correlation is assumed for simulation.
