DFRC with Improved Communication-Sensing Trade-off via Private Subcarrier Permutations and Pairing with Antennas
Zhaoyi Xu, Athina P. Petropulu
Dual function radar communication (DFRC) systems can achieve significant improvements in spectrum efficiency, system complexity and energy efficiency, and are attracting a lot of a…
Phased Array With Improved Beamforming Capability via Use of Double Phase Shifters
Zhaoyi Xu, Athina P. Petropulu
The passive electronically scanned array (PESA) is widely used due to its simple structure and low cost. {Its antenna weights have unit modulus and thus, only the weights phases ca…
Sparse Antenna Array Design for MIMO Radar Using Softmax Selection
Konstantinos Diamantaras, Zhaoyi Xu, Athina Petropulu
MIMO transmit arrays allow for flexible design of the transmit beampattern. However, the large number of elements required to achieve certain performance using uniform linear array…
Learning to Select for MIMO Radar based on Hybrid Analog-Digital Beamforming
Zhaoyi Xu, Fan Liu, Konstantinos Diamantaras +2
In this paper, we propose an energy-efficient radar beampattern design framework for a Millimeter Wave (mmWave) massive multi-input multi-output (mMIMO) system, equipped with a hyb…
