Abstract :
We consider the optimal strategy for erasing symbols in concatenated coding schemes. This erasing strategy uses a posteriori likelihoods of RS symbols to determine erasures which maximize the probability of decoding correctly. Some properties of performance of this strategy are presented. Erasing rules for decoding the same received word more than once are also examined
