Multidimensional Variational Line Spectra Estimation
Qi Zhang, Jiang Zhu, Ning Zhang +1
The fundamental multidimensional line spectral estimation problem is addressed utilizing the Bayesian methods. Motivated by the recently proposed variational line spectral estimati…
Grid-less Variational Direction of Arrival Estimation in Heteroscedastic Noise Environment
Qi Zhang, Jiang Zhu, Yuantao Gu +1
Horizontal line arrays are often employed in underwater environments to estimate the direction of arrival (DOA) of a weak signal. Conventional beamforming (CB) is robust but has wi…
Matrix Completion from Quantized Samples via Generalized Sparse Bayesian Learning
Jiang Zhu, Zhennan Liu, Qi Zhang +2
The recovery of a low rank matrix from a subset of noisy low-precision quantized samples arises in several applications such as collaborative filtering, intelligent recommendation…
Gridless Multisnapshot Variational Line Spectral Estimation from Coarsely Quantized Samples
Ning Zhang, Jiang Zhu, Zhiwei Xu
Due to the increasing demand for low power and higher sampling rates, low resolution quantization for data acquisition has drawn great attention recently. Consequently, line spectr…
One-bit LFMCW Radar: Spectrum Analysis and Target Detection
Benzhou Jin, Jiang Zhu, Qihui Wu +2
One-bit radar, performing signal sampling and quantization by a one-bit ADC, is a promising technology for many civilian applications due to its low-cost and low-power consumptions…
