This paper introduces applying power exponential software pre-equalization in visible light communication system based on a commercial phosphorescent white LED for high speed transmission. Simulations and experiments are carried out to verify the performance of power exponential pre-equalization. 2.08Gbit/s VLC transmission over 1m free-space distance is implemented through experimental demonstration...
In this paper, we present a high-speed visible light communication (VLC) system based on a single commercially available phosphorescent white light-emitting diode (LED). In this system, a preequalization circuit is used to extend the modulation bandwidth, and a differential output receiver is utilized to reduce the system noise. With adaptive bit and power allocation and orthogonal frequency-division...
