Abstract :
Asymptotic nonexistence bounds for unequal error protecting codes with two protection levels are considered. We show that the improved estimates, reported by Litsyn on the possible distance distributions for codes, may sometimes yield sharper upper bounds than the previously known ones, for both nonlinear and linear codes having two protection levels
