Some continuous multidestination ARQ schemes for high error rate conditions

A class of relatively simple continuous ARQ schemes with repeated transmissions suitable for multidestination communications under high error rate conditions is studied. In real applications, the throughput performance can be optimised by choosing the best scheme along those investigated with respect to the round-trip delay, the number of receivers and the block error probability. Results show that the optimal scheme may offer a far better performance than Morris´s scheme for multidestination environments.
