| Abstract: |
This paper is dedicated to error‐correction coding using polar codes. First, we design an error‐correction approach including two cascade non‐binary polar coding (NB‐CPolar) structures and a cyclic redundancy check (CRC) code. Second, we propose a low‐complexity decoding algorithm based on non‐binary successive cancellation list (NB‐LSCL) decoding. In order to improve the correction performance, during the level‐2 NB‐Polar decoding process, we propose to prioritize the CRC decision, retaining the paths with higher reliability, before performing the level‐1 NB‐Polar decoding operation. Simulation results demonstrate that compared with the baseline scheme, the NB‐CPolar encoder and NB‐LSCL decoding algorithm significantly improve the error correction performance.
