Abstract
Irregular LDPC codes have a construction which allows one to obtain a number of codes with different length from a single prototype code with a parity check matrix given by H=[Hz Hi], where Hz specifies the well-known zigzag pattern in the corresponding Tanner graph. The parity check matrices for longer codes are obtained as [Hz′Πdiag(Hi, . . . , Hi)], where Hz′ specifies a longer zigzag pattern depending on the number of matrices Hi used, and Π represents some permutation. This allows one to construct the decoder for a longer code by reusing hardware components developed for decoding the prototype code.
