Two-Hop Secure Communication Using an Untrusted Relay: A Case for Cooperative Jamming
—We consider a source-destination pair that can communicate only through an unauthenticated intermediate relay node. In this two-hop communication scenario, where the cooperation...

Energy-Efficient Cooperative Relaying over Fading Channels with Simple Relay Selection
We consider a cooperative wireless network where the source broadcasts data to relays, some or all of which cooperatively beamform to forward the data to the destination. The netw...

Cooperative Filter-and-Forward Beamforming for Frequency-Selective Channels with Equalization
Most of the existing literature on cooperative relay networks has focused on frequency– nonselective channels or frequency–selective channels with multi–carrier transmission...

On the Optimality of the ARQ-DDF Protocol
The performance of the automatic repeat request-dynamic decode and forward (ARQ-DDF) cooperation protocol is analyzed in two distinct scenarios. The first scenario is the multiple...
