The Secrecy Capacity Region of the Gaussian MIMO Multi-Receiver Wiretap Channel
In this paper, we consider the Gaussian multiple-input multiple-output (MIMO) multi-receiver wiretap channel in which a transmitter wants to have confidential communication with ...

Robust Beamforming for Security in MIMO Wiretap Channels with Imperfect CSI
—In this paper, we investigate methods for reducing the likelihood that a message transmitted between two multiantenna nodes is intercepted by an undetected eavesdropper. In part...

Secrecy capacity of a class of orthogonal relay eavesdropper channels
The secrecy capacity is developed for a class of relay channels with orthogonal components and a passive eavesdropper node. The relay and destination receive signals from the sourc...

A flexible high-throughput hardware architecture for a gaussian noise generator
In this paper a exible, high-throughput, low-complexity additive white gaussian noise (AWGN) channel generator is presented. The proposed generator employs a Mersenne-Twister to g...
