摘要 介绍了偏振模色散现象,提出了基于低密度奇偶校验码(LDPC)的改进译码算法,并在此基础上设计了LDPC译码增强系统。对系统建模,通过与原有译码模型的仿真比较,分析其在系统误码纠错能力上的改进。 This paper introduces the phenomenon of polarization mode dispersion, proposes an improved de-coding algorithm based on low density parity check （LDPC） codes, on the basis of this, it designs the LDPCdecoding enhancement system. The paper builts the system model, by comparison with the original decodingsimulation model to analyze the improvement of system error correction capability.
