چکیده
-MIMO-OFDM system has been currently recognized as one of the most competitive technology for 4G mobile wireless systems. MIMOOFDM 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.
