Device Activity Detection and Channel Estimation for Millimeter-Wave Massive MIMO
Yinchuan Li, Yuancheng Zhan, Le Zheng +1
Millimeter-Wave Massive MIMO is important for beyond 5G or 6G wireless communication networks. The goal of this paper is to establish successful communication between the cellular…
Radar and Communication Co-existence: an Overview
Le Zheng, Marco Lops, Yonina C. Eldar +1
Increased amounts of bandwidth are required to guarantee both high-quality/high-rate wireless services (4G and 5G) and reliable sensing capabilities such as automotive radar, air t…
Interference Removal for Radar/Communication Co-existence: the Random Scattering Case
Yinchuan Li, Le Zheng, Marco Lops +1
In this paper we consider an un-cooperative spectrum sharing scenario, wherein a radar system is to be overlaid to a pre-existing wireless communication system. Given the order of…
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…
Millimeter-Wave Beamformed Full-dimensional MIMO Channel Estimation Based on Atomic Norm Minimization
Yingming Tsai, Le Zheng, Xiaodong Wang
The millimeter-wave (mmWave) full-dimensional (FD) MIMO system employs planar arrays at both the base station and user equipment and can simultaneously support both azimuth and ele…
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…
Adaptive Interference Removal for Un-coordinated Radar/Communication Co-existence
Le Zheng, Marco Lops, Xiaodong Wang
Most existing approaches to co-existing communication/radar systems assume that the radar and communication systems are coordinated, i.e., they share information, such as relative…
Improved NN-JPDAF for Joint Multiple Target Tracking and Feature Extraction
Le Zheng, Xiaodong Wang
Feature aided tracking can often yield improved tracking performance over the standard multiple target tracking (MTT) algorithms with only kinematic measurements. However, in many…
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…
Demixing Sines and Spikes: Robust Spectral Super-resolution in the Presence of Outliers
Carlos Fernandez-Granda, Gongguo Tang, Xiaodong Wang +1
We consider the problem of super-resolving the line spectrum of a multisinusoidal signal from a finite number of samples, some of which may be completely corrupted. Measurements of…
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…
