A note on p -nary adjacent-error-correcting codes
B. Elspas · IEEE Transactions on Information Theory · 1960
Binary group codes described by Abramson permit the correction of all single errors and all double errors in adjacent digits, with the use of significantly fewer check digits than codes capable of correcting all double-bit errors. This note considers the generalization of Abramson's codes to thep-nary case, where a symbol alphabet consisting of the digits0, 1, \cdots , p - 1is used for transmission,pbeing a prime number. Examples of suchp-nary codes are given, as well as necessary conditions for their existence. These codes bear the same relation to thep-nary Golay codes as Abramson's codes do to the familiar Hamming codes. Some as yet unanswered questions are raised, and suggestions for further possible generalizations are given.
