Title:
POLARIZATION CODE DECODING METHOD, DECODER AND DECODING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/042271
Kind Code:
A1
Abstract:
Provided in the present application are a method, a decoder and a decoding device for a polarization code. The method comprises: obtaining M log likelihood ratio values corresponding to each first decoded sequence in a current level of decoding, according to L first decoded sequences obtained by an upper level decoding; for any first decoded sequence, determining L optimal decoding paths according to the M log likelihood ratio values corresponding to the first decoded sequence in the current level of decoding, wherein the first decoded sequence corresponds to 2M decoding paths in the current level of decoding, and the L optimal decoding paths are decoding paths whose branch metrics are smaller than the branch metrics of other coding paths in the 2M coding paths, each branch metric being determined on the basis of M log likelihood ratio values; and for the L first decoded sequences, determining L second decoded sequences corresponding to the current level of decoding in the L×L optimal decoding paths. With the method of the application, the decoding efficiency can be improved without increasing the decoding complexity.
