PACKET ERROR CORRECTION CODE DECODING METHOD, APPARATUS, STORAGE MEDIUM, AND ELECTRONIC DEVICE

Embodiments of the present invention provide a packet error correction code decoding method, apparatus, storage medium, and electronic device, relating to the technical field of packet error correction code communication technology; the method comprises: determining the number of iterative decoding layers according to the size of a submatrix in a check matrix, said check matrix consisting of a sequence of packet error correction codes; on the basis of a target check node in a target iterative decoding layer, performing target processing of a target variable node associated with said target check node; if all of the results of said target processing are non-establishment of all hard decisions, then performing the target processing on all other variable nodes in the target iterative decoding layer; if all of the results of said target processing are non-establishment of a hard decision, then performing target processing on the variable nodes in the other iterative decoding layers corresponding to the variable n
