基于统计特性的LDPC码分析识别研究

从统计角度出发,提出对LDPC码分析思路和初步方法,在仿真的情况下进行验证。利用LDPC码作为分组码的特性,通过统计和对统计特性的分析,在一定程度上克服传统方法———解高斯方程法的局限性,实现了对LDPC码部分特性分析。同样适用于其他分组码的分析识别。

Research on Identification of LDPC Code Based on Statistical Properties

In this Paper, the ideas and methods of the analysis of LDPC （Low Density Parity Check） code have been put forward from a statistical point, and they have been confirmed in the simulation conditions . The methods analyse some LDPC code＇ s properties in statistical view u- sing the way taking LDPC code as a kind of block code. To a certain extent, the ideas and methods overcome the limitations of Gaussian equation method, a the traditional method, and solve some problems of achieving part characterization of the LDPC code. The ideas and methods are also applicable to the analysis and identification of other block codes.
