A Modulo Sampling Hardware Prototype and Reconstruction Algorithm Evaluation
Jiang Zhu, Junnan Ma, Zhenlong Liu +3
Analog-to-digital converters (ADCs) play a vital important role in any devices via manipulating analog signals in a digital manner. Given that the amplitude of the signal exceeds t…
One-Bit-Aided Modulo Sampling for DOA Estimation
Qi Zhang, Jiang Zhu, Fengzhong Qu +1
Modulo sampling has recently drawn a great deal of attention for cutting-edge applications, due to overcoming the barrier of information loss through sensor saturation and clipping…
Line Spectral Estimation via Unlimited Sampling
Qi Zhang, Jiang Zhu, Fengzhong Qu +1
Frequency Modulated Continuous Wave (FMCW) radar has been widely applied in automotive anti-collision systems, automatic cruise control, and indoor monitoring. However, conventiona…
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…
Gridless Line Spectral Estimation with Multiple Measurement Vector via Variational Bayesian Inference
Qi Zhang, Jiang Zhu, Peter Gerstoft +2
Line spectral estimation (LSE) from multi snapshot samples is studied utilizing the variational Bayesian methods. Motivated by the recently proposed variational line spectral estim…
