PHASED ERROR CORRECTING PERFECT CODES
Bhu Dev Sharma, BHUPINDER KAUR · Journal of Cybernetics · 1977
Random errors increase with the increase in word length. The random errors which are spread over the word in blocks of suitable lengths are defined as phased errors. Correction of phased errors is considered, and special types of codes correcting double phased errors that are perfect in the sense that they correct all single and double phased errors and no others ate systematically defined and studied. Decoding algorithms, nonbinary extensions, modifications, weight enumerators and generalizations for correcting more than two phased errors are also investigated.
