Title:
CODING METHOD AND APPARATUS, AND DECODING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/273815
Kind Code:
A1
Abstract:
A coding method and apparatus, and a decoding method and apparatus, which are used for generating a polar code matching higher-order modulation. In the present application, the coding method comprises: determining the number S of symbols according to the number L of coded bits and the number B of energy levels, wherein S is S1 or S2, S1 = L/B, and S2 = L/2B; determining K information sub-channels from a coding sequence according to the number S of symbols, the number B of energy levels, and a reliability sequence; and according to the K information sub-channels, encoding K information bits and outputting a bit sequence, wherein the K information sub-channels are selected from among candidate sub-channels according to the order of the reliability of the candidate sub-channels, and the candidate sub-channels are S1 sub-channels or 2×S2 sub-channels in a sub-sequence having an energy level of i in the coding sequence.
