Abstract: Visible light communication (VLC) is a promising and eco-friendly complementary technology to the existing radio frequency (RF) based communication system. However, the performance of VLC based system is limited by dispersive characteristics of the VLC channel, and restricted modulation bandwidth of light emitting diode (LED). To mitigate the ISI, orthogonal time frequency space (OTFS) modulation is proposed in the literature. However, it has been found that the performance analysis of OTFS over multipath VLC channels has not been investigated. This paper investigates the performance of OTFS over static multipath channels for the VLC system. Simulations performed over the standardized IEEE 802.15.7 VLC channel indicate that OTFS with message passing detector delivers an approximate 6 dB SNR gain at BER of 10−4 over the conventional orthogonal frequency division multiplexing (OFDM) scheme with minimum mean square error (MMSE) based detector. © 2020 IEEE.
