Abstract： |
The invention relates to a method for designing systematic codes of an irregular low density parity check code and communication system thereof, wherein a semi-random generation method is employed to obtain a base check matrix, then each element of the basis matrix is expanded to a window pane sub-matrix, thus irregular LDPC code check matrix can be obtained, which first conducts pre-transformation to row/line weight distribution pattern when producing the Hb, and a specific matrix whose non-zero row/line element number is greater than 1 to create a systematic code to simplify the encoder arrangement. |
