Currently, most channel coding algorithms are based on Turbo codes and Low-Density Parity-Check codes (LDPC codes), which can effectively reduce the error rate and improve the reliability of signals. However, in practical situations, the characteristics of communication channels and channel noise factors will affect the performance of coding and decoding algorithms, and therefore, it is necessary to improve the coding and decoding algorithms.The aim of this study is to propose an improved channel coding algorithm to enhance its performance and stability. Firstly, by analyzing the advantages and disadvantages of Turbo codes and LDPC codes, combined with the characteristics of communication channels and error rate requirements, the most suitable coding algorithm will be determined. Secondly, using polynomial codes and iterative decoding techniques to improve the coding algorithm and enhance its error correction performance and decoding speed. Finally, the effectiveness of the algorithm will be verified through simulation experiments.This research will provide a new idea and method for high-performance signal processing in fields such as mobile communication and wireless networks and has a certain practical application value.Keywords: channel coding algorithm, Turbo codes, LDPC codes, polynomial codes, iterative decoding.
