The Capacity of a Relay Channel, Both With and Without Delay

The Capacity of a Relay Channel, Both With and Without Delay

In this correspondence, we point out the incorrectness of an upper bound in van der Meulen (Advances in Applied Probability, vol. 3, no. 1, pp. 120-154, 1971) and report the correct relay capacity for one of the examples given there. We also show that, when viewed as a relay-without-delay channel, t...

Zusammenfassung:In this correspondence, we point out the incorrectness of an upper bound in van der Meulen (Advances in Applied Probability, vol. 3, no. 1, pp. 120-154, 1971) and report the correct relay capacity for one of the examples given there. We also show that, when viewed as a relay-without-delay channel, the capacity of this channel is strictly larger than its classical relay capacity.
