At the beginning of 60 s of last century,Gallager,the student of Shannon issued the concept and a whole set of method for decoding of LDPC code at the first time in the world.But the LDPC code had not been on the focus of our research with its super performance until the end of the last century,for the improvement of the LDPC decoding theory and the development of the computer technology.When we research the QC-LDPC code,we realize that many kinds of LDPC codes do not only have one set of 1,and this leads the question that the result of CNU belongs to which memory module.Meanwhile,because of the difference of all column initial position of every submatrix and the large number of the submatrix of the check matrix,we can not easily solidify the location of each 1 and this will lead errors which can not be easily found and the low efficiency of exploitation.To solve this question and generalize the module,this thesis researches the character of the arrangement rules of 1in submatrix,finds the commonness of variable,and realizes the design of the general-purpose module.
