Abstract

The present disclosure provides a decoder, a decoding method, , wherein the decoder is configured to perform layered iterative decoding based on a check matrix corresponding to a codeword to be decoded, and the decoder comprises: a first memory and a message updating circuit; the first memory is configured to store a posterior probability message; the message updating circuit is configured to: sequentially read a posterior probability message corresponding to each non-zero sub-matrix of a current layer from the first memory in a first reading order; the first reading order is determined according to a position of each non-zero sub-matrix of the current layer; obtain an updated posterior probability message corresponding to each non-zero sub-matrix of the current layer based on the posterior probability message corresponding to each non-zero sub-matrix of the current layer in a current iteration; sequentially write the updated posterior probability message corresponding to each non-zero sub-matrix of the current layer into the first memory in a first writing order; the first writing order is determined according to the first reading order.
