On the delay and throughput of digital and analog network coding for wireless broadcast
— We address the problem of exchanging broadcast packets among multiple wireless terminals through a single relay node. The objective is to evaluate the delay and throughput gain...

Transmission of common, public and confidential messages in broadcast channels with multiple antennas
Abstract-- We study the Gaussian multiple-input multipleoutput (MIMO) wiretap channel, which consists of a transmitter, a legitimate user, and an eavesdropper. In this channel, the...

Cooperation with an untrusted relay: a secrecy perspective
We consider the communication scenario where a source-destination pair wishes to keep the information secret from a relay node despite wanting to enlist its help. For this scenario...

Multiple-antenna multiple-relay system with precoding for multiuser transmission
Multi-hop relaying will play a central role in next generation wireless systems. In this paper a novel relaying strategy that uses multiple-input multiple-output (MIMO) relays in ...

One- and Two-Way Decode-and-Forward Relaying for Wireless Multiuser MIMO Networks
— In this paper, we propose multiuser multiple-input multiple-ouput (MIMO) one- and two-way relaying protocols. Several wireless MIMO node pairs are establishing either unidirect...
