Robust Downlink Beamforming in Multiuser MISO Cognitive Radio Networks
Ebrahim A. Gharavol, Ying-Chang Liang, Koenraad Mouthaan
This paper studies the problem of robust downlink beamforming design in a multiuser Multi-Input Single-Output (MISO) Cognitive Radio Network (CR-Net) in which multiple Primary User…
Design of Learning Based MIMO Cognitive Radio Systems
Feifei Gao, Rui Zhang, Ying-Chang Liang +1
This paper addresses the design issues of the multi-antenna-based cognitive radio (CR) system that is able to operate concurrently with the licensed primary radio (PR) system. We p…
On the Relationship Between the Multi-antenna Secrecy Communications and Cognitive Radio Communications
Lan Zhang, Rui Zhang, Ying-Chang Liang +2
This paper studies the capacity of the multi-antenna or multiple-input multiple-output (MIMO) secrecy channels with multiple eavesdroppers having single/multiple antennas. It is kn…
