摘要：
In this paper, the performance of an indoor visible light communication (VLC) system in the presence of Gaussian-plus-Laplacian additive noise is investigated. Initially, a realistic VLC system model is established by considering the effects of channel gain and Gaussian-plus-Laplacian additive noise. Theoretical expressions of the average bit error rate (ABER) and average channel capacity are derived, respectively. To show the system performance at a high signal-to-noise ratio, the asymptotic ABER expression is obtained. Numerical results show that all theoretical results agree well with the simulation results. Moreover, the effects of Laplacian noise scale parameter, dimming target, Lambertian order, and the radius of the receiver zone on system performance are also discussed.
