In the context of Internet of Things and 5G communication, ensuring the accuracy and reliability of data transmission is critical, especially as the future 6G communication system places a greater emphasis on highly reliable transmission. However, the existing error correction schemes for 5G are found to be insufficient in their error correction capability for the 6G environment. To address this issue, this paper proposes an enhanced error correction scheme, which is an improvement over existing methods. This scheme is based on a combination of cyclic redundancy check (CRC) codes and Polar Codes, optimized through the use of a Successive Cancellation Decoding algorithm. The objective is to enhance the error detection and correction capabilities during data transmission. By leveraging the synergistic application of CRC and Polar Codes, the proposed scheme introduces enhanced sequence interleaving techniques and error pattern analysis, which significantly improve the decoding algorithm’s performance and accuracy. Experimental results demonstrate that the proposed scheme, in comparison to the traditional Successive Cancellation Decoding algorithm, effectively reduces the block error rate (BLER), thereby enhancing the high reliability of data transmission.
