Construction of Systematic Codes for Unidirectional Error Control
November 1995 (vol. 44 no. 11)
pp. 1331-1334

Abstract—Construction methods for systematic t-UEC d-UED codes are proposed. These are codes that are able to simultaneously correct up to t unidirectional errors and detect from t+ 1 up to d unidirectional errors. Both encoding and decoding procedures are provided. The efficiency of the codes is discussed and compared to the efficiencies of known corresponding codes with slightly stronger or weaker error control capabilities.
