Secrecy in Cooperative Relay Broadcast Channels
E. Ekrem, S. Ulukus
We investigate the effects of user cooperation on the secrecy of broadcast channels by considering a cooperative relay broadcast channel. We show that user cooperation can increase…
A New Upper Bound on the Capacity of a Class of Primitive Relay Channels
Ravi Tandon, Sennur Ulukus
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 i.i.d. sequence , which is…
Capacity of a Class of Diamond Channels
Wei Kang, Sennur Ulukus
We study a special class of diamond channels which was introduced by Schein in 2001. In this special class, each diamond channel consists of a transmitter, a noisy relay, a noisele…
A New Achievability Scheme for the Relay Channel
Wei Kang, Sennur Ulukus
In this paper, we propose a new coding scheme for the general relay channel. This coding scheme is in the form of a block Markov code. The transmitter uses a superposition Markov c…
