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…
On Gaussian MIMO BC-MAC Duality With Multiple Transmit Covariance Constraints
Lan Zhang, Rui Zhang, Ying-Chang Liang +2
Owing to the structure of the Gaussian multiple-input multiple-output (MIMO) broadcast channel (BC), associated optimization problems such as capacity region computation and beamfo…
Cognitive Beamforming Made Practical: Effective Interference Channel and Learning-Throughput Tradeoff
Rui Zhang, Feifei Gao, Ying-Chang Liang
This paper studies the transmit strategy for a secondary link or the so-called cognitive radio (CR) link under opportunistic spectrum sharing with an existing primary radio (PR) li…
Optimal Beamforming for Two-Way Multi-Antenna Relay Channel with Analogue Network Coding
Rui Zhang, Ying-Chang Liang, Chin Choy Chai +1
This paper studies the wireless two-way relay channel (TWRC), where two source nodes, S1 and S2, exchange information through an assisting relay node, R. It is assumed that R recei…
Robust Cognitive Beamforming With Partial Channel State Information
Lan Zhang, Ying-Chang Liang, Yan Xin +1
This paper considers a spectrum sharing based cognitive radio (CR) communication system, which consists of a secondary user (SU) having multiple transmit antennas and a single rece…
