Non orthogonal multiple access (NOMA) is used to maintain the throughput and fairness in communication system. It is also investigated in context of visible light communication (VLC). The bit-error-rate (BER) and channel performance like important parameters are improved by using equalizer. In this paper, NOMA multiple input multiple output (MIMO) based VLC system is analyzed using zero forcing equalizer with successive interface cancellation (ZF-SIC) and minimum mean square error (MMSE) equalizer with successive interface cancellation (MMSE-SIC) to enhance BER performance. Simulation results showed that MMSE-SIC improves BER by 3dB of signal-to-noise ratio (SNR).
