Abstract :
The authors discuss combined channel coding and error concealment schemes for digital audio broadcasting (DAB). Comparison of two coding schemes showed that the robustness against hostile reception conditions of a digital broadcast transmission can effectively be increased by applying unequal protection (UEP) and a simple concealment of residual bit errors (muting and repetition of some scalefactors)
