Clock Data Recovery for Short-Distance Visible Light Communications

摘要

This paper presents a simple clock data recovery (CDR) scheme that enhances the bit error rate (BER) performance for wireless audio applications through short-distance visible light communications (VLCs). The whole systems and algorithms are evaluated with FPGA boards, LEDs, and photo-diodes. The resultant BER is measured as less than 10~(-8) at the distance of 35 cm between a transmitter and a receiver.
