基于动态索引的LDPC卷积码译码器研究

摘要

文章利用滑窗译码算法的特点，针对随机LDPC卷积码设计了一种基于周期动态索引的译码器。这种译码器通过借助内嵌函数，将其中的部分模块合为一体，具有结构简单、运算效率高、通用性和可移植性强的特点。仿真实验表明该方案可以取得良好的纠错性能。%This paper uses the characteristics of the sliding window decoding algorithm to design a new decoder based on periodic dynamic index for LDPC convolutional codes. By means of the embedded function, the some module of the decoder is integrated into a whole. Therefore, it has the characteristics of simple structure, high operation efifciency, high universality and portability. Simulation results show that the proposed scheme can achieve good error correction performance.
