Class Information
Number: 714/784
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 > Reed-solomon code
Description: Subject matter where the block code consists of K data and N-K check symbols, where N is an arbitrary number and K is less than N, and where each symbol is made of J binary bits encoded with a generator polynomial g(x) for the code and a field generating polynomial M(x) which defines the Galois field.
