In this paper, we study the secrecy precoding problem for a cognitive multiple-input-multiple-
output multiple-eavesdropper (MIMOME) wiretap system. The problem is studied with an …

In this paper, we consider a multi-input-multi-output (MIMO) wiretap channel with a multi-
antenna eavesdropper, where a private cooperative jammer is employed to improve the …

We consider the problem of secure communication in the multiuser downlink with an
external eavesdropper. The transmitter simultaneously transmits concurrent information …

In this paper, the secure transmission strategy for a multi-input-single-output multi-
eavesdropper system with coexistence of a secure user (Bob) and a normal user (NU) is …

We study a multi-antenna wiretap channel, where the transmitter does not have perfect
knowledge about the channels to the eavesdropper. The transmitter only knows that the …

A Gaussian multiple-antenna wiretap channel model is considered, where there exists a
transmitter equipped with multiple antennas, a legitimate receiver equipped with a single …

We evaluate the effective secrecy throughput of the multiple-input multiple-output multiple-
antenna eavesdropper (MIMOME) wiretap channel with antenna selection at the legitimate …

This paper considers the artificial noise (AN) scheme, proposed by Goel and Negi for
securing wireless communications over multiple-input multiple-output multiantenna …

In this paper, we investigate optimal power allocation to achieve perfect secrecy capacity in
Gaussian MIMO wire-tap channels. The number of antennas in the MIMO wire-tap channel is …

Secrecy on the physical layer is a promising technique to simplify the overall cross-layer
secrecy concept. In many recent works on the multiple antenna wiretap channel, perfect …
