An achievable rate region for a class of Broadcast-Relay Networks
Sadaf Salehkalaibar, Leila Ghabeli, Mohammadreza Aref · 2010
In this paper we define Broadcast Relay Networks (BRN) with two relays. There are a transmitter, two relays and two receivers in the network. We find an achievable rate region for it by considering full cooperation between relays. We use symmetric relaying method at relays and Marton's broadcast code construction for the transmitter. We will show that Kramer's rate region for Broadcast Relay Channel (BRC), Ghabeli's rate for symmetric two-relay network, and Marton's rate region for Broadcast Channel are special cases of our achievable rate region.
