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 …

The capacity region of the multiple access channel with correlated sources remains an open
problem. Cover, El Gamal and Salehi gave an achievable region in the form of single-letter …

In this paper, we introduce multiple access relay channel with orthogonal components from
the senders to the relay receiver and from the senders and relay to the receiver. Our model …

We consider the discrete memoryless symmetric primitive relay channel, where, a source
wants to send information to a destination with the help of a relay and the relay can …

We consider two-way relaying in a Gaussian diamond channel, where two terminal nodes
wish to exchange information using two relays. A simple baseline protocol is obtained by …

This paper is concerned with the capacity of Gaussian orthogonal multi-access relay
channel (OMARC) where multiple sources communicate with one destination in the …

In this paper, we obtain a general achievable rate region for discrete memoryless multiple‐
access relay channel (DM‐MARC) with common message via partial decode and forward …

A class of diamond networks is studied where the broadcast component is orthogonal and
modeled by two independent bit-pipes. New upper and lower bounds on the capacity are …

We consider the multiple access channel (MAC) assisted by N parallel relays that only have
buffering and amplifying capabilities. For this channel, we derive the capacity region …

We obtain a new upper bound on the capacity of a class of discrete memoryless relay
channels. For this class of relay channels, the relay observes an iid sequence T, which is …
