Location-Based Equalization for OFDM Indoor Visible Light Communication Systems

摘要

In indoor visible light communication (VLC) systems based on orthogonal frequency division multiplexing (OFDM), we propose a novel location-based equalization (LBE) concept to counteract multi-path effects. Different implementation methods are also discussed. Results show that the LBE design, especially based on only a line-of-sight link, can effectively equalize OFDM multi-path signals and improve system bit error rate performance at different indoor locations.
