Abstract
In this paper, an indoor optical wireless CDMA system based on zero cross correlation (ZCC) code is investigated under the influence of ambient light noise. We consider line of sight communication links between multiple emitters and receivers. We first establish an analytical expression of bit error rate and then validate its estimations with the simulated results. The finding results show a great matching between the theoretical estimations and simulation results. Whereas at BER of 10-9, there is no difference in terms of the effective received power while there is a variation of about only 1 dB at channel attenuation.
