N2 - We discussed the BER performances versus SNR variation for every level of interference of LED neighbours in MIMO VLC network serving 6 user equipments (UEs). The MIMO configuration is 2x3 and 3x2, based on NHS-OFDM and NOMA schemes. The required power ratio for a successful NOMA of MIMO-2x3 is 1:2:4 while MIMO-3x2 configuration needs 1:2 of power ratio. To obtain BER below FEC limit, the minimum SNR should be above 20 dB for each MIMO configuration with the maximum interference level allowed is 3% for MIMO-3x2 and 1 % for MIMO-2x3. In case where the SNR is 30 dB, the maximum interference level allowed are 13% and 10% for MIMO-3x2 and MIMO-2x3, respectively, to maintain the BER below FEC limit.
