Super-Resolution mmWave Channel Estimation using Atomic Norm Minimization
Hongyun Chu, Le Zheng, Xiaodong Wang
We propose super-resolution MIMO channel estimators for millimeter-wave (mmWave) systems that employ hybrid analog and digital beamforming and generalized spatial modulation, respe…
Coordinated Multicell Multicast Beamforming Based on Manifold Optimization
L. Zhou, L. Zheng, X. Wang +2
Multicast beamforming is a key technology for next-generation wireless cellular networks to support high-rate content distribution services. In this paper, the coordinated downlink…
Joint Design of Overlaid Communication Systems and Pulsed Radars
Le Zheng, Marco Lops, Xiaodong Wang +1
The focus of this paper is on co-existence between a communication system and a pulsed radar sharing the same bandwidth. Based on the fact that the interference generated by the ra…
Super-Resolution Delay-Doppler Estimation for OFDM Passive Radar
Le Zheng, Xiaodong Wang
In this paper, we consider the problem of joint delay-Doppler estimation of moving targets in a passive radar that makes use of orthogonal frequency-division multiplexing (OFDM) co…
Does -minimization outperform -minimization?
Le Zheng, Arian Maleki, Haolei Weng +2
In many application areas we are faced with the following question: Can we recover a sparse vector from its undersampled set of noisy observations $y \in \ma…
