Low density parity check codes are a class of linear block error - correcting codes that can be defined by the very sparse parity - check matrix . their error performance approach shannon limits Ldpc碼(低密度校驗碼)是一類可以用非常稀疏的奇偶校驗矩陣定義的線性分組糾錯碼,具有逼近香農(nóng)限的性能。
It s true that many developers did their own revision control , but there was no official linux cvs archive that linus torvalds checked code into and others could pull from 實際上,很多開發(fā)者實現(xiàn)了他們自己的修正控制器,但是并沒有官方的linux cvs檔案庫,讓linus torvalds檢查加入代碼,并讓其他人可以由此獲得代碼。
A cyclic check code used to check and correct the burst error appeared in the transmission procedure of binary information sequence . it is one of the error check codes in common use for computer disc memory 用來檢查、糾正二進制信息序列在傳輸過程中出現(xiàn)的突發(fā)錯誤的一種循環(huán)校驗碼,它是計算機磁盤存儲器常用的錯誤校驗碼之一。
The code cowboy feels that checking code into source control takes too long , storing configuration data outside of the code itself takes too long , communicating with anyone else takes too long … you get the idea 代碼牛仔認為把代碼提交到源碼控制系統(tǒng)太麻煩,把配置信息存貯在代碼之外太麻煩,和其它人交流太麻煩… …你懂我的意思吧。
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 低密度奇偶校驗( ldpc )碼是基于稀疏校驗矩陣的線性分組碼,它最初由gallager于1962年提出,當時并未受到人們的重視。
