Cooperative Jamming for Secure Communications in MIMO Relay Networks
Jing Huang, A. Lee Swindlehurst
Secure communications can be impeded by eavesdroppers in conventional relay systems. This paper proposes cooperative jamming strategies for two-hop relay networks where the eavesdr…
Prescient Precoding in Heterogeneous DSA Networks with Both Underlay and Interweave MIMO Cognitive Radios
Amitav Mukherjee, A. Lee Swindlehurst
This work examines a novel heterogeneous dynamic spectrum access network where the primary users (PUs) coexist with both underlay and interweave cognitive radios (ICRs); all termin…
Optimization of UAV Heading for the Ground-to-Air Uplink
Feng Jiang, A. Lee Swindlehurst
In this paper we consider a collection of single-antenna ground nodes communicating with a multi-antenna unmanned aerial vehicle (UAV) over a multiple-access ground-to-air wireless…
Robust Secure Transmission in MISO Channels Based on Worst-Case Optimization
Jing Huang, A. Lee Swindlehurst
This paper studies robust transmission schemes for multiple-input single-output (MISO) wiretap channels. Both the cases of direct transmission and cooperative jamming with a helper…
Solutions for the MIMO Gaussian Wiretap Channel with a Cooperative Jammer
S. Ali. A. Fakoorian, A. Lee Swindlehurst
We study the Gaussian MIMO wiretap channel with a transmitter, a legitimate receiver, an eavesdropper and an external helper, each equipped with multiple antennas. The transmitter…
