PROBLEM TO BE SOLVED: To reduce the scale of a circuit on a parity check side in parity monitoring for inserting a parity computed result computed over one frame to the prescribed time slot of the next frame. SOLUTION: This system is provided with the two systems of circuits 11 and 12 ...
Low-density parity-check (LDPC) codes are one of the most promising families of codes to replace the Goppa codes originally used in the McEliece cryptosystem. In fact, it has been shown that by using quasi-cyclic low-density parity-check (QC-LDPC) codes
A parity bit, also referred to as parity check, is an extra bit added to a set of binary data bits for the purpose of error detection during data transmission. The parity bit is used to check if the number of 1s in a data string is even or odd, resulting in two types: even parity...

PURPOSE:To improve the reliability of a parity check result by checking the propriety of a parity check device on a reception side by setting ON-OFF a parity- error occurrence bit, provided to the reception side, in response to an indication from a transmission side. CONSTITUTION:Parity checker...
columns corresponding to parity bits; and the base graph further comprises: two punctured highest-degree variable nodes; an additional one-degree parity bit formed by a parity of the two punctured highest-degree variable nodes; and a plurality of check nodes corresponding to rows in the base PCM...
Example methods are disclosed for decoding low-density parity-check (LDPC) encoded data, involving applying an expanded parity check matrix to generate decoded data, wherein −1 repr
