DEFINITION

Classification: 714/781

Code based on generator polynomial:

(under subclass 752) 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.
