Abstract
The present invention provides a low-density parity-check code decoding method and a decoder. The method is configured to solve correct code words of input signals according to a predetermined low-density parity-check matrix. The method comprises: according to the low-density parity-check matrix, multi-time decoding trying in the number of predetermined decoding trying times is performed, the multi-time decoding trying at least comprises first decoding trying comprising first decoding scheduling and second decoding trying comprising second decoding scheduling. The second decoding trying is adjacently continued to the first decoding trying. There is one group of the first decoding scheduling which is not included in the second decoding scheduling.
