Binary bch codes

http://match.stanford.edu/reference/coding/sage/coding/bch_code.html One of the key features of BCH codes is that during code design, there is a precise control over the number of symbol errors correctable by the code. In particular, it is possible to design binary BCH codes that can correct multiple bit errors. See more In coding theory, the Bose–Chaudhuri–Hocquenghem codes (BCH codes) form a class of cyclic error-correcting codes that are constructed using polynomials over a finite field (also called Galois field). … See more There are many algorithms for decoding BCH codes.
