摘要
针对围长影响准循环低密度奇偶校验码译码性能的问题,提出了基于电压图方法研究QC-LDPC码围长.该法简化研究围长的计算,并通过电压图的生成树边和非生成树边不同赋值,证明出提升图围长[g]范围的影响.
Abstract
In order to solve the problem that girth affects the decoding performance of quasi-cyclic low-density parity-check codes,a voltage diagram method is proposed to study the girth of QC-LDPC codes.This method simplifies the calculation of the girth of the study,and proves the influence of increasing the girth range of the voltage graph by different assignment of the generating and non-generating edges of the voltage graph.
