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