A half-duplex relay channel consisting of two relays in a diamond topology is studied. In
contrast to full-duplex systems, it is shown that time should be optimally allocated among …

In this paper, a dual-hop communication system composed of a source S and a destination
D connected through two non-interfering half-duplex relays, R 1 and R 2, is considered. In …

This paper considers the Gaussian half-duplex relay channel (G-HD-RC): a channel model
where a source transmits a message to a destination with the help of a relay that cannot …

This paper considers a Gaussian relay network where a source transmits a message to a
destination with the help of N half-duplex relays. The information theoretic cut-set upper …

We consider the diamond network where a source communicates with the destination
through N non-interfering half-duplex relays. Deriving a simple approximation to the capacity …

This paper studies networks that consist of N half-duplex relays assisting the communication
between a source and a destination. In ISIT'12 Brahma et al. conjectured that in Gaussian …

We study the capacity of the full‐duplex bidirectional (or two‐way) relay channel with two
nodes and one relay. The channels in the forward direction are assumed to be different (in …

In this paper, we consider the full-duplex and half-duplex Gaussian relay channels where
the noises at the relay and destination are arbitrarily correlated. We first derive the capacity …

We study the capacity of the full-duplex bidirectional (or two-way) relay channel with two
nodes and one relay. The channels in the forward direction are assumed to be different (in …

A simple diamond half-duplex relay network composed of a source, two decode-and-forward
half-duplex relays, and a destination is considered, where a direct link between the source …
