Abstract
This application discloses a polar encoding method and apparatus and a polar decoding method and apparatus, to apply polar codes to source coding and decoding, to improve source coding and decoding performance. The method may be implemented by using the following steps: obtaining to-be-encoded source bits; performing first polar encoding on the to-be-encoded source bits to obtain encoded source bits, where the first polar encoding includes first transformation and second transformation, the first transformation is a polarization transformation, a mother code length corresponding to the first transformation is Ns, the polarization transformation is performed on the to-be-encoded source bits to obtain first source bits, and the second transformation is performed on the first source bits to obtain the encoded source bits; determining assistance information based on the first source bits; and outputting a source coding codeword, where the source coding codeword includes the encoded source bits and the assistance information.
