Visible light communications (VLC) are a short-range wireless transmission technology and one of the candidate technologies for 6G. However, interference has a significant effect on system performance. This paper proposes an improved MMSE algorithm to mitigate the interference in MIMO-OFDM-based VLC systems. The performance is investigated in the presence of interference from other users. The simulation results indicate that the proposed interference mitigation technique is more reliable in multi-user systems.
