Methods and apparatus for polar code encoding, and methods and apparatus for polar code decoding, and methods readable by computers and communication systems

Abstract

The invention of the method, the encoding mechanism, and the computer-readable means used in wireless communication, aims to meet the transmission demands of large amounts of data and improve system throughput. The method includes the following steps: acquiring K bits to be encoded, the length of the master code N, and the first sequence, where the first sequence includes the sequence number of the polarized subchannels, the sequence number of the N polarized subchannels arranged in the first sequence based on the confidence of the N polarized subchannels, N = * , K < N, and κ, II, and N are positive integers; and determines, based on the first sequence, K polarized subchannels used to contain K bits to be encoded, and performs polarization encoding on the K bits to be encoded to receive and output the encoded bit sequence. The invention also proposes a method, a decoding mechanism for polarization codes, and a communication system.
