Abstract :
A relay-without-delay channel in which each transmitted relay symbol can depend on all its past as well as present received symbols is investigated. A general upper bound on the capacity of the channel is established. A lower bound on the capacity for the additive white Gaussian noise relay-without-delay channel is introduced and is shown to coincide with the upper bound for a certain range of parameter values
