ABSTRACT
The emerging visible light communication (VLC) technology, which has the advantages of high communication speed, security, and indoor lighting, has become a research hot point of indoor wireless communication technology. As the only forward error correction (FEC) coding technology theoretically proven to achieve Shannon's capabilities, Polar codes are adopted to improve communication performance in VLC systems. This paper proposes concatenated CRC-aided polar codes (CA-Polar codes) schemes with interleaving techniques for VLC systems. The results show that it can effectively correct errors in VLC systems. Compared to the polar codes, the CA-Polar codes are more suitable as the inner code of the concatenated polar codes. The experimental results demonstrate that the RS-CA-Polar scheme has a more significant descent slope. Under BER (10-6), it requires 1.3dB less signal-to-noise ratio than BCH-CA-polar scheme.
