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. The most common ones follow this general outline: 1. Calculate the syndromes sj for the received vector 2. Determine the number of errors t and the error locator polynomial Λ(x) from the … See more • Blahut, Richard E.
