  • Abstract
    A procedure for optimal symbol-by-symbol binary block-code decoding is presented: it uses the spectral Walsh-Hadamard transformation. The dimension of the Walsh-Hadamard basis is equal to that of dual codes. The realisation of the described procedure, using the fast Walsh-Hadamard transformation application, is seen to be the most efficient in terms of computational complexity for high-rate code decoding, in comparison with known symbol-by-symbol decoding procedures
