Abstract :
A novel, fast decoder for the binary quadratic residue code of length 23, or equivalently the famous Golay code is proposed. The core is a new idea to determine the syndrome weight. The decoding algorithm can be implemented with a parallel design, and the decoder based on this algorithm is not only very efficient but also of low area cost. It promises a binary Golay decoder which is faster than available decoders.
