Enhancing Secrecy with Multi-Antenna Transmission in Wireless Ad Hoc Networks
Xi Zhang, Xiangyun Zhou, Matthew R. McKay
We study physical-layer security in wireless ad hoc networks and investigate two types of multi-antenna transmission schemes for providing secrecy enhancements. To establish secure…
Rethinking the Secrecy Outage Formulation: A Secure Transmission Design Perspective
Xiangyun Zhou, Matthew R. McKay, Behrouz Maham +1
This letter studies information-theoretic security without knowing the eavesdropper's channel fading state. We present an alternative secrecy outage formulation to measure the prob…
On the Distribution of MIMO Mutual Information: An In-Depth Painlevé Based Characterization
Shang Li, Matthew R. McKay, Yang Chen
This paper builds upon our recent work which computed the moment generating function of the MIMO mutual information exactly in terms of a Painlevé V differential equation. By explo…
On the Design of Artificial-Noise-Aided Secure Multi-Antenna Transmission in Slow Fading Channels
Xi Zhang, Xiangyun Zhou, Matthew R. McKay
In this paper, we investigate the design of artificial-noise-aided secure multi-antenna transmission in slow fading channels. The primary design concerns include the transmit power…
