2.32 Gbit/s phosphorescent white LED visible light communication aided by two-staged linear software equalizer

Abstract

We proposed two-staged linear software equalizer to be applied in high speed visible light communication system. Through the experimental demonstration, we implemented 2.32 Gbit/s VLC transmission based on a phosphorescent white LED with 450MHz bandwidth and 1m transmission distance. The other key technologies are adaptive bit and power loading OFDM, differential amplification PINs and maximum ratio combing algorithm. As far as we know, this is the highest data rate implemented based on a phosphorescent white LED in VLC system.
