Embodiment Construction

[0032] The present invention is aimed at the decoding method and decoder of the low-density parity-check code, and proposes that when decoding the codeword (codeword), it includes at least two decoding operations before and after two iterations, and uses different decoding schedules, so as to be more effective in the follow-up In the iterative decoding operation, it can more effectively use part of the information that has been solved and accumulated in the previous decoding operation, speed up the convergence speed of the iterative code operation, or obtain a higher throughput within the same iteration limit (throughput).

[0033] The present invention proposes a decoding scheduling plan to improve decoding efficiency, but the determined decoding scheduling is not limited to a specific decoding method operated at the backend. That is, for example, under the premise of a given decoding schedule, any applicable known decoding mechanism may be used for decoding, which may includ...

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.

Description

technical field [0001] The present invention relates to a decoding method and decoder for low density parity check codes, and in particular to a decoding method and decoder for low density parity check codes with variable decoding schedule. Background technique [0002] In 1962, the low-density parity-check code (LDPC code) was proposed by Gallager, and it was proved that its error correction capability was very close to the theoretical maximum, the Shannon Limit, but there was no specific implementation method. [0003] In recent years, in the research and development of wireless communication, in response to the needs of modern technology, the decoding method of the low density parity check code has been considered again. The demands of modern technology are, for example, those of video, which require the transmission of large amounts of data. Based on the large increase of transmission data, data signals are transmitted in parallel to facilitate the wireless communicatio...
