<p>Embodiments of the present invention provide a Polar code decoding method and decoder. The decoding method includes: segmenting a first Polar code having a length of N into m mutually coupled second Polar codes, where a length of each second Polar code is N/m, N and m are integer powers of 2, and N > m; independently decoding the m second Polar codes to acquire decoding results of the m second Polar codes; and obtaining a decoding result of the first Polar code according to the decoding results of the m second Polar codes. In the embodiments of the present invention, a Polar code having a length of N is segmented into multiple segments of mutually coupled Polar codes; the segmented Polar codes are independently decoded; and results of the independent decoding are jointly processed to obtain a decoding result of an original Polar code; in this way, there is no need to sequentially decode N bits, and flexibility of Polar code decoding can be improved.</p> |
