Description

technical field

[0001] The invention relates to the field of error correction control, in particular to a turbo product code decoding method, device, decoder and computer storage medium. Background technique

[0002] As an iterative decoding algorithm based on soft input and soft output, turbo product code has become a research hotspot in the field of channel coding because its error correction performance is very close to the Shannon limit. In related technologies, soft decoding and decoding algorithms are mainly used as the decoding method of Turbo product codes. However, when the number of errors is small, the power consumption of soft decoding and decoding algorithms is high, and it is more suitable to use hard decoding and decoding at this time. algorithm. However, when the bit error rate is low, there will be a bit error floor when using the hard decoding algorithm to decode the Turbo product code, and the cause of the error level is mainly the generation of deadlock ...
