Optimal Power Allocation for Secrecy Fading Channels Under Spectrum-Sharing Constraints
Junwei Zhang, Mustafa Cenk Gursoy
In the spectrum-sharing technology, a secondary user may utilize the primary user's licensed band as long as its interference to the primary user is below a tolerable value. In thi…
Secure Relay Beamforming over Cognitive Radio Channels
Junwei Zhang, Mustafa Cenk Gursoy
In this paper, a cognitive relay channel is considered, and amplify-and-forward (AF) relay beamforming designs in the presence of an eavesdropper and a primary user are studied. Ou…
Collaborative Relay Beamforming for Secrecy
Junwei Zhang, Mustafa Cenk Gursoy
In this paper, collaborative use of relays to form a beamforming system and provide physical-layer security is investigated. In particular, decode-and-forward (DF) and amplify-and-…
Collaborative Relay Beamforming for Secure Broadcasting
Junwei Zhang, Mustafa Cenk Gursoy
In this paper, collaborative use of relays to form a beamforming system with the aid of perfect channel state information (CSI) and to provide communication in physicallayer securi…
Relay Beamforming Strategies for Physical-Layer Security
