Class Information
Number: 714/777
Name: Error detection/correction and fault detection/recovery > Pulse or data error handling > Digital data error correction > Forward correction by block code > Hamming code
Description: Subject matter where there are m information code elements and k error check code elements such that there are sufficient check elements to correct a single error and the k check elements are determined by even parity checks in conjunction with element values appearing in certain selected information positions where each of the elements of the code group must be in a parity check subgroup with one or more of the check elements and no two different code elements having exactly the same set of check elements associated with it.
