Abstract :
This paper introduces a type-I hybrid ARQ scheme for the Z-channel, based on a class of codes which can correct t asymmetric errors and further detect d (d > t) more. The specific parameters of the ARQ schemes are considered and an upper bound on the probability of undetected error is derived. We give a couple of detailed examples based on classic inner error correcting codes. They show good behavior of this scheme in terms of error rate and throughput
