摘要 针对LDPC码在光纤通信系统中的应用,提出将相位估计算法与LDPC译码算法相结合,研究表明将M次幂载波相位估计算法输出的调制信息估计值进行软解调后,能有效地与LDPC软译码算法相结合。 For LDPC code in the application of optical fiber communication system, this paper puts forward the phase estimation algorithm and the combination of LDPC decoding algorithm, studies have shown that will Mth power carrier phase estimation algorithm output estimates of modulation information for soft demodula- tion, effectively combined with soft decoding of LDPC algorithm.
