- among the linear block codes, rs code is an important one widely used in modern digital communications, which can correct both random and bursty errors with the most powerful error-correcting capability
rs码是一种典型的纠错码,在线性分组码中,它具有最强的纠错能力,既能纠正随机错误,也能纠正突发错误。 - ldpc ( low density parity check ) code is a kind of linear block code that defined by very sparse parity matrix or tanner graph, and it is also called gallager code since gallager initially presented it
ldpc(lowdensityparitycheck)码是一类用非常稀疏的校验矩阵或二分图定义的线性分组纠错码,最初由gallager发现,故亦称gallager码。 - the linear block code is called a binary low-density parity-check code if it is based on a sparse parity-check matrix . this sort of code was originally proposed by dr . gallager in 1962, which cannot attract a large amount of interest at that time
低密度奇偶校验(ldpc)码是基于稀疏校验矩阵的线性分组码,它最初由gallager于1962年提出,当时并未受到人们的重视。 - some results on the undetected error probability of linear codes for pure error-detection are, at present, generalized for both error detection and correction . an analytic formula is obtained to calculate the undetected error probability of linear block codes for simultaneous error detection and correction
