Abstract

The invention discloses a symbol flipping decoding method and system suitable for a multivariate polar code, and relates to the technical field of channel coding and decoding, and the method comprises the steps: obtaining a decoding symbol sequence and an LLR value corresponding to the decoding symbol sequence, carrying out the precoding verification of the decoding symbol sequence, and if the verification is passed, ending the decoding, the decoding symbol sequence and the LLR value corresponding to the decoding symbol sequence are obtained by decoding based on an initialized SC-MS decoder; if the decoding symbol sequence does not pass the verification, calculating a flipping position and a flipping symbol value based on an LLR value corresponding to the decoding symbol sequence, storing the flipping position and the flipping symbol value in a flipping matrix, and dynamically flipping the decoding symbol based on a pre-established SC-MS symbol flipping decoder and the flipping matrix; and pre-coding check and maximum flipping decoding frequency judgment are carried out again, if the check is passed or the maximum flipping decoding frequency is reached, decoding is ended, otherwise, dynamic flipping is carried out on the decoding symbol again, and the SC-MS decoding performance of the multivariate polarization code is improved.
