摘要

The polar codes (PCs) has been shown to effectively enhance the transmission distance of ultraviolet communication (UVC) systems, however, an optimized decoding algorithm for PCs is required to reduce the interference and the path-loss propagation attenuation. In this paper, a successive cancellation list (SCL) decoder scheme is proposed and implemented over the classic successive cancellation (SC) decoding algorithm by extending decoding path using the UV path loss particle model. Numerical simulations are performed to show the performance improvement of SCL decoding scheme for PCs in UVC that combined with cyclic redundancy check (CRC) joint detection decoding.
