Unidirectional covering codes

A code C/spl sube/Z/sup n//sub 2/, where Z/sub 2/={0,1}, has unidirectional covering radius R if R is the smallest integer so that any word in Z/sup n//sub 2/ can be obtained from at least one codeword c/spl isin/C by replacing either 1s by 0s in at most R coordinates or 0s by 1s in at most R coordi...
