摘要:
由于可见光通信中可能会受到很多噪声干扰,信道编码受到了广泛的重视,它是重要的通信纠错方法,为改善可见光通信的信道译码性能,提高信息传输效率,降低译码复杂度,采用一种将 RS 码与 LDPC 码级联的方案。RS 码具有很强的处理突发错误的能力,LDPC 码具有接近香浓极限的良好性能。该方案实现简单,复杂度低。经仿真结果表明,该方法与未编码时相比,误码率 低,纠错能力有明显提升,而且比较级联码中 LDPC 码不同码长的性能,误码率为 10-3 时,编码增益提高 2 dB 左右,适合可见光通信的实际应用的要求。
Abstract:
As visible light communication may be affected by a lot of noise,channel coding receives wide attention it is an important means of communication error correction. To improve the performance of channel decoding,increase the rate of information transmission and reduce the decoding complexity in the visible light communication,this paper uses a scheme with RS code and LDPC code cascaded. RS code has a good ability to handle unexpected errors,LDPC code has a good performance that is close to the Shannon limit. The scheme is easy to implement with low complexity. Simulation results shows that bit error rate is lower than uncoded,the ability of error correction has more promotion obviously,and the performance compares to different lengths of LDPC code in cascaded codes,when the bit error rate reaches 10-3 ,it can improve the gain amounting to about 2 dB. So it is suitable for visible light communication requirements in practical application.
