Low-Rank and Row-Sparse Decomposition for Joint DOA Estimation and Distorted Sensor Detection
Huiping Huang, Qi Liu, Hing Cheung So +1
Distorted sensors could occur randomly and may lead to the breakdown of a sensor array system. We consider an array model within which a small number of sensors are distorted by un…
Nonlinear Tensor Ring Network
Xiao Peng Li, Qi Liu, Hing Cheung So
The state-of-the-art deep neural networks (DNNs) have been widely applied for various real-world applications, and achieved significant performance for cognitive problems. However,…
Accurate DOA Estimation Based on Real-Valued Singular Value Decomposition
Hui Cao, Qi Liu
In this paper, an accurate direction-of-arrival (DOA) estimator is developed based on the real-valued singular value decomposition (SVD) of covariance matrix. Unitary transform on…
Target Localization with Jammer Removal Using Frequency Diverse Array
Qi Liu, Jingwei Xu, Zhi Ding +1
A foremost task in frequency diverse array multiple-input multiple-output (FDA-MIMO) radar is to efficiently obtain the target signal in the presence of interferences. In this pape…
Image Denoising by Random Interpolation Average with Low-Rank Matrix Approximation
Qi Liu, Wing-Shan Tam, Chi-Wah Kok +1
With the wide deployment of digital image capturing equipment, the need of denoising to produce a crystal clear image from noisy capture environment has become indispensable. This…
