In this paper the BER performances are analyzed of a STBC encoded secured multiuser MIMO-OFDM wireless communication System. The 2X2 multi-antenna supported MIMO-OFDM system implements RSA cryptographic algorithm and ZF and MMSE based linear pre channel equalization schemes with deployment of various digital modulations (16-QAM, 16-PSK and 16-DPSK) over AWGN and Rayleigh fading channel. In this work the channel state information (CSI) is exploited at the transmitter side. It has been observed that the system under investigation outperforms with 16-QAM digital modulation and pre-MMSE channel equalization scheme and shows worst performance with 16-DPSK and pre-ZF. It is also observable that under situation of without implementing the pre channel equalization technique, the system provides satisfactory performance with 16-QAM and MMSE.
