摘要：

Low-Density Parity-Check (LDPC) codes are applied into ultraviolet (UV) communication system. In this paper, LU decomposition algorithm is adopted as the channel coding method. Simulations are conducted to compare the performance of different LDPC decoding algorithms in UV communication system. The results show that the belief propagation (BP) based UV system has a better bit error ratio (BER) performance than the one with the bit flipping (BF) decoding algorithm. Moreover, communication system performance trade-offs among transmission distance, path loss, frame length and BER are studied.
