%X MIMO-OFDM system has been currently recognized as one of the most competitive technologyfor 4G mobile wireless systems. MIMO-OFDM system can compensate for the lacks of MIMOsystems and give play to the advantages of OFDM system. In this paper, a general Quasiorthogonal space time block code (QOSTBC) structure is proposed for multiple-input multipleoutput¨Corthogonal frequency-division multiplexing (MIMO-OFDM) systems for 4X4 antennaconfiguration. The signal detection technology used in this paper for MIMO-OFDM system isZero-Forcing Equalization (linear detection technique).In this paper the analysis of high level of modulations (i.e. M-PSK for different values of M) onMIMO-OFDM system is presented. Here AWGN and Rayleigh channels have been used foranalysis purpose and their effect on BER for high data rates have been presented. The proposedMIMO-OFDM system with QOSTBC using 4X4 antenna configuration has better performance interms of BER vs SNR than the other systems.
