An integrated PIN-array receiver for visible light communication

摘要

This paper first designs and demonstrates an integrated receiver for a visible light communication (VLC) system based on RGB LED and an array of silicon PIN diode detectors. The system uses a maximal ratio combining (MRC) algorithm to enhance system performance. The novel integrated PIN diode array design yields a high date rate of 1.2 Gbit s(-1) by 16QAM-OFDM based on a commercially available RGB LED in a VLC system with bit error rate under a 7% pre-forward-error-correction (FEC) threshold of 3.8. x. 10(-3) after 30 cm free-space transmission. The results show that the use of integrated antennas in VLC systems will become a trend in the future.
