We consider symmetric two-user Gaussian interference channel with common messages. We derive an upper bound on the sum capacity, and show that the upper bound is tight in the low i…
On the Capacity Region of Broadcast Packet Erasure Relay Networks With Feedback
Quan Geng, Hieu T. Do, Rui Wu +3
We derive a new outer bound on the capacity region of broadcast traffic in multiple input broadcast packet erasure channels with feedback, and extend this outer bound to packet era…
