Abstract
An error correction and detection technique provides a correction code for correcting single bit errors as well as detecting but not correcting two adjacent bits in error. A received word, which may contain errors, is multiplied by a parity check matrix to produce a syndrome corresponding to one of first and second mutually exclusive sets of syndromes if the received word contains at least one error, each single bit error in the received bit word corresponding one-to-one with a member of the first of the sets of syndromes and each two bit adjacent error corresponding non-uniquely to a member of the second of the sets of syndromes. A syndrome containing all zeros is produced if the received word contains no errors. One bit data errors in the received word are corrected, two bit errors are reported, and no action is taken if the word contains no errors.
