How ldpc works
Web27 jun. 2024 · In this method, the sender sends a redundant error-correcting code along with the data frame. The receiver performs necessary checks based upon the additional redundant bits. If it finds that the data is free from errors, it executes error-correcting code that generates the actual frame. Web不同LDPC码的构造方法都是为了实现如下的目标 ：① 增大Girth值；② 减小编码复杂度。 1、LDPC码的基本概念 LDPC码 是使用一个 稀疏的 、 非系统的 校验矩阵 H 定义的 线性码 。 行重 ： H 矩阵中每行中'1'的个数； 列重 ： H 矩阵中每列中'1'的个数。 规则LDPC码 ：各行的行重、各列的列重一致； 不规则LDPC码 :行重 或 列重不一致。 1.1 规则LDPC码
