Class Information
Number: 714/781
Name: Error detection/correction and fault detection/recovery > Pulse or data error handling > Digital data error correction > Forward correction by block code > Code based on generator polynomial
Description: Subject matter where a code word c(x), where x is a unit delay operator, is generated by dividing a delayed version of the data polynomial d(x), i.e.,. xnd(x), by a generator polynomial, g(x), and subtracting the remainder from the delayed version of the data polynomial, thereby producing a code word that is a multiple of the generator polynomial, and where the data polynomial d(x) is such that positions within the block correspond to powers of x and data values at the positions correspond to polynomial coefficient values.
