In this paper, an effort has been made to elucidate BER performance of a secured MIMO MCCDMA wireless communication system. The simulated system under present paper implements Space Time Block Coding (STBC) and MIMO Beamforming schemes with three channel encoding schemes (1/2-rated convolutional and CRC and BCH) and four digital modulations (BPSK, DPSK QPSK and QAM). In this system, transmission of text data has been secured with concatenated implementation of Vigenere Cipher and RSA cryptographic algorithm. It is anticipated from the numerical results that the STBC and MIMO Beamforming scheme adopted MCCDMA system with 1/2-rated convolutional channel encoding technique outperforms in BPSK digital modulation under AWGN and Raleigh fading channels.
