MIMO-OFDM system has been currently recognized as one of the most competitive technology for 4G mobile wireless systems. MIMO-OFDM system can compensate for the lacks of MIMO systems and give play to the advantages of OFDM system. In this paper, a general orthogonal space time block code (OSTBC) structure is proposed for multiple-input multiple-output-orthogonal frequency-division multiplexing (MIMO-OFDM) systems for 8X8 antenna configuration. The signal detection technology used in this paper for MIMO-OFDM system is Zero-Forcing Equalization (linear detection technique). In this paper the analysis of high level of modulations ( i.e M-PSK for different values of M) on MIMO-OFDM system is presented. Here AWGN and Rayleigh channel have been used for analysis purpose and their effect on BER for high data rates has been presented. The proposed MIMO-OFDM system with OSTBC using 8X8 antenna configuration has better performance in terms of BER vs SNR than the other systems.
