WebSep 24, 2016 · DECODING BINARY BCH CODES A binary BCH code is a subset of the set of binary n-tuples. The subset is usually defined by considering the n-tuples as coefficients of a binary polynomial, i.e., if (a,+,,~~,- 1 *,a,- r) is a binary n-tuple, n-l f(X) = F UiXi is the binary polynomial associated with it.
