Symbol reconstruction methods by applying Galois Field arithmetic to Reed Solomon codewords have been disclosed. Reconstruction methods by applying n-valued reversing logic functions are also provided. A correct codeword can be selected from calculated codewords by comparing a calculated codeword with the Reed-Solomon codeword in error. A correct codeword can also be found by comparing a codeword in error with possible (p,k) codewords. Non Galois Field Reed Solomon coders are disclosed. Methods for correcting symbols in errors that have been identified as being in error are provided. Apparatus that implement the error correction methods are disclosed. Systems, including communication and storage systems that use the disclosed methods are also provided. |
