| 7. | 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。 |
| 8. | 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
