Interference Management for Multi-cell Indoor Visible Light Communication Systems

Abstract

Visible optical communication (VLC) is a novel wireless communication technology based on white light-emitting diode. VLC is a promising 6G and short-range wireless transmission technology. However, interference has a significant effect on system performance. This paper proposes an improved MMSE algorithm to mitigate interference in MIMO-OFDM-based VLC systems. This study examines its performance in combination with interference from other factors. Therefore, simulation results show that the proposed anti-jamming technique works better in systems with more than one user.
