Abstract :
Bounds on the rate of grain-correcting codes are presented. The lower bounds are Gilbert-Varshamov-like ones, whereas the upper bounds improve on the previously known result by Mazumdar et al.. Constructions of t-grain-correcting codes of length n for certain values of n and t are discussed.
