ABSTRACT:
A data coding method produces codewords with a scheme that changes for different codewords, and decodes codewords with a scheme that remains constant for all codewords. The coding method receives k user bits, codes the user bits to produce k+r output bits, corrupts any one of the output bits, and accurately reproduces at least k−r−1 user bits. Codewords coded using the appropriate initial conditions are output. For each codeword, the appropriate initial conditions are appended to the codeword coded therefrom.
