Abstract: A decoding method includes: decoding first to-be-decoded information based on a first decoder to obtain a first decoding result that includes first soft information or a first hard output; and correcting the first decoding result based on a first correction model to obtain a corrected first decoding result of the first to-be-decoded information. The first correction model is obtained through training based on training data that includes a training decoding result and a corrected training decoding result. The training decoding result is a decoding result obtained after the first decoder decodes training to-be-decoded information, and the corrected training decoding result is a corrected decoding result corresponding to the training decoding result. In this way, after a decoder performs decoding, a decoding result can be corrected based on a correction model.
