CONSTITUTION: A system for constituting a check matrix for a regular low density parity check code includes a first square matrix generation part(421), a second square matrix generation part(422), a coding block setting part(423), a matrix calculator(430), and a check bit generation part(...
A method of generating parity data based on a low-density parity check matrix and an apparatus therefore. The method of generating parity data is based on a parity check matrix H having p codewords of length c, each codeword being divided in a message word of length m and parity data of...
A check matrix of LDPC codes is formed by a combination of a (P×P) unit matrix, a matrix in which one to several 1s of the unit matrix are substituted with 0, a matrix in which they are cyclically shifted, a matrix, which is the sum of two or more of them, and a (P×P) ...
But for 4 disk, Pool count and fault tolerance is needed to be considered, we can’t just use the formula: maximum=(n-1)/n*maximum, please check the following documentation, the maximum efficiency volume of 4 disks is also 66.7(two-thirds)% rather than 75%, so the compute mode of ...
