In this paper, a comprehensive study has been made to evaluate the performance of 2 × 2 multiantenna configured MIMO NOMA wireless communication system. The simulated system incorporatesvarious types of signal processing techniques (Channel coding: LDPC & Convolutional, Digital modulation: QPSK, DQPSK & 4-QAM, Signal detection:ML decoding based QR channel decomposition aided SIC). On considering downlink transmission of encrypted color image of each of two users in a hostile fading channel, it is noticeable from MATLAB based simulation study that the system is very much robust and effective in retrieving transmitted color images underutilization of LDPC channel coding and 4-QAM digital modulation techniques.The performance of the simulated downlink MIMO NOMA wireless communication system has been evaluated in terms of bite error rate(BER) under scenario of various receive signal to noise ratio(SNR) ranging from 0dB to 16dB.
