Unidirectional Bit/Byte Error Control

Research output: Contribution to journalArticlepeer-review


This paper defines a new class of unidirectional errors, named t/u -unidirectional errors, which affect at most / bits confined to at most u bytes of the code word. Codes that are capable of detecting, locating and correcting tl\-unidirectional errors are presented. Lower bounds on the number of checkbits required for t/1 -unidirectional error detection and location are also presented.
