Investigation of the Performance of Single Carrier Visible Light Communication Systems in Multi-Path Fading Optical Channels

In this paper, the performances of single carrier visible light communication systems are analyzed in multi-path fading optical channels. Distortions in the data sent due to the multipath optical channel are corrected by linear and nonlinear channel equalizers. Computer simulations are performed to compare the equalizers with each other and to obtain the uncoded and encoded bit error rate performances. As a result of the simulation results, it was observed that the Convolutional coded and Turbo coded system eliminates the error floor at each iteration.
