AbstractThis paper proposes a computational platform for simulations of visible light communication (VLC) systems. Special emphasis is placed on the modeling of light-emitting diode and its nonlinear aspects, optical channel, and photodiode. In addition, the equalization performance of VLC systems is assessed using adaptive filters, such as Volterra decision-feedback equalizer. Bit error rate results indicate that adaptive nonlinear techniques outperform linear-in-parameter approaches when it comes to coping with VLC nonlinearities.
