"WebApr 12, 2013 · Abstract: Explicit nonasymptotic upper bounds on the sizes of multiple-deletion correcting codes are presented. In particular, the largest single-deletion correcting code for q-ary alphabet and string length is shown to be of size at most (q n -q)/ { (q-1) (n-1)}. An improved bound on the asymptotic rate function is obtained as a corollary. " - Deletion correcting code
