DATA PROCESSING IN CHANNEL DECODING

WIPO Patent Application WO/2020/146990

A1

Embodiments of the present disclosure relate to a device, a method, an apparatus and a computer readable storage medium for data processing. In example embodiments, a method of data processing is provided. The method comprises obtaining, from a channel decoding process, a first input and a second input on which a sum-product operation is to be performed, the sum-product operation including one or more sub-operations. The method further comprises determining a set of mapping relationships for approximating at least one of the one or more sub-operations. The method further comprises determining, based on the first input, the second input and the set of mapping relationships, a first result of the sum-product operation, and continuing the channel decoding process based on the first result. As such, embodiments of the present disclosure can improve error correcting capabilities of Low Density Parity Check (LDPC) code, Polar code, Reed-Muller (RM) code or the like.
