ABSTRACT:
A system (e.g., Fiber Channel Error Detecting Code (FC-EDC)) that maps the “standard” Hamming codes onto the bits of a 33-bit control block is provided. The system employs a “rotation” of the check positions in a two-dimensional parity-check matrix for the FC-EDC. The specification discloses a computer-implemented program to test further modifications and permutations of the “standard” distance-4 parity-check matrix to yield an FC-EDC with enhanced error-detecting properties, designed to detect the most likely errors in the known physical environment. By using a parity-check matrix with the “rotation” property, certain error-detecting properties of the parity-check matrix are ensured, and the computation time for searching for a matrix with enhanced error-detecting properties becomes much shorter.
