In order to address the issue of data transmission errors in integrated cireuits caused by stronginterferenee in industrial environments and to achieve reliable communication in such conditions,an improvedand innovative intereaving and coding/decoding method is proposed based on the principle that errolcorreetion codes can enhance the integrity of essential data signal transmission. This method optimizes the UART protocol for high-reliability transmission , and utilizes CRC checksums and reliable encoding modules todetect and correct transmission errors in the data, thereby enabling integrated systems to better adapt tocomplex and dynamic industrial environments.Perormance testing of the improved interleaving and decodingalgorithm is conducted using Al signal aequisition as an example , demonstrating the algorithm's significanterror detection and correction capabilities for data transmission in strongly interlered environments.
