The task assigned to the Capital University of Aeronautics and Astronautics was the design of error-correcting codes, a limited role, roughly equivalent to a quarter of the overall task, was assigned to the smaller Intelligent and Automation Lab at Yanhua University.
Even so, the workload was substantial.
Error-correcting codes refer to codes capable of identifying or correcting errors on the receiving end during the transmission process.
These codes come with error detection and correction capabilities, requiring the addition of redundant code elements to the original code word, to enlarge the differences between code words. This involves transforming the original code word into a code word with a certain amount of redundancy according to certain rules, and establishing certain relationships between each code word.
