Abstract
In wireless optical systems, Visible Light Communication (VLC) is one of the most popular communication systems. In this study, a Bit Error Rate (BER) performance comparison is given for Variable On-Off Keying (VOOK) and Variable Pulse Position Modulation (VPPM) which are extensively used in VLC systems. According to simulation and theoretical results, it is shown that the BER performances of systems are similar. In this paper, an ambient light noise is added to Additive White Gaussian Noise to extend the BER performance analysis. From simulation results, it is obtained that the impact of ambient light noise is very high for VOOK while it is quite poor for VPPM. Hence, the BER performance of VPPM has better than that of VOOK under ambient light noise.
