Problems solved by technology

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. At this time, it is more suitable to use hard decoding and decoding. algorithm
However, when the bit error rate is low, using the hard decoding algorithm to decode the Turbo product code will cause a bit error level, and the cause of the bit error level is mainly the generation of deadlock or deadlock-like structure

Abstract

The embodiment of the invention discloses a decoding method of a Turbo product code, which comprises the following steps of: obtaining a receiving code word of the Turbo product code, and carrying outiterative decoding on the receiving code word for a set first iterative decoding frequency; judging a decoding result of iterative decoding of the first iteration times according to a first decodingrule to obtain a decoding identifier for representing the decoding result; and carrying out error correction processing on the Turbo product code after iterative decoding of the first number of iterations according to the decoding identifier. The embodiment of the invention further discloses a decoding device of the Turbo product code, a decoder and a computer storage medium.

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 ...
