Title:
DECODING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/063217
Kind Code:
A1
Abstract:
A decoding method and apparatus. The method comprises: acquiring an LLR sequence corresponding to a bit sequence to be decoded (401), wherein the LLR sequence comprises 2w LLRs, the bit sequence is obtained by means of performing polar code encoding on a first bit sequence, and w is an integer greater than or equal to 1; determining an LDPC code check matrix corresponding to the bit sequence (402); on the basis of the LDPC code check matrix corresponding to the bit sequence, using an LDPC code decoder to decode the LLR sequence so as to obtain a first decoding result (403); according to the first decoding result, obtaining a decoding bit sequence (404). By using the described method, for a bit sequence to be decoded that is obtained by means of polar code encoding, the use of an LDPD code decoder to decode an LLR sequence corresponding to the bit sequence is enabled by means of determining an LDPC code check matrix corresponding to the bit sequence, thereby enabling polar code decoding and LDPC code decoding to achieve common mode decoding, and saving on hardware overheads.
