Abstract
An encoder provides (2t−1) redundant symbols in a sequence of n coded symbols, and a decoder corrects up to t erroneous symbols in the sequence of n coded symbols corrupted by a plurality of symbol errors. The decoder uses an improved decoding method, the method solving a plurality of matrix equations, each matrix equation associated with a hypothetical location of error. By monitoring a plurality of solutions associated with hypothetical locations of error, a processor determines the actual number of errors, the locations of the erroneous symbols in the sequence of n symbols, and the erroneous symbol value at each error location. The improved decoder includes erasure processing and a correct symbol determination method similar to erasure processing.
