ABSTRACT:
Methods and apparatus for creating codewords of n-valued symbols with one or more n-valued check symbols are disclosed. Associating the codewords with a matrix allows for detection of one or more symbols in error and the location of such symbols in error. Methods to reconstruct symbols in error from other symbols not in error are also disclosed. Systems for using the methods of error detection and error correction by symbol reconstruction are also disclosed. Using two or more matrices to determine check symbols is also provided.
