Achievable Rates for Gaussian Degraded Relay Channels With Non-Vanishing Error Probabilities
Achievable Rates for Gaussian Degraded Relay Channels With Non-Vanishing Error Probabilities
This paper revisits the Gaussian degraded relay channel, where the link that carries information from the source to the destination is a physically degraded version of the link that carries information from the source to the relay. The source and the relay are subject to expected power constraints. The ε-capacity …
