Abstract :
In this paper, the application of spread codes in indoor visible lighting communication (VLC) system is investigated. We choose four spread codes, pseudo-noise (PN) binary-valued code, Walsh code, m-sequence and gold code and compare their bit error rate (BER) performances on directed line of sight (LOS) channel and diffuse channel, respectively. The experiment validates that VLC using spread code is indeed feasible to alleviate the effect of multi-path dispersion.
