Nested array design of extended coprime sets for DOA estimation of non-circular signals

Dongqi Chen, Kun Ye, Chuanxi Xing +2

In recent years, direction of arrival estimation utilizing non-circular signals has become a focal point for scholarly research. To enhance the degrees of freedom (DOF) in receiver…

Sparse Array Design for Dual-Function Radar-Communications System

Huiping Huang, Linlong Wu, Bhavani Shankar +1

The problem of sparse array design for dual-function radar-communications is investigated. Our goal is to design a sparse array which can simultaneously shape desired beam response…

Sparse Array Beamformer Design via ADMM

Huiping Huang, Hing Cheung So, Abdelhak M. Zoubir

In this paper, we devise a sparse array design algorithm for adaptive beamforming. Our strategy is based on finding a sparse beamformer weight to maximize the output signal-to-inte…

Convergence Analysis of Consensus-ADMM for General QCQP

Huiping Huang, Hing Cheung So, Abdelhak M. Zoubir

We analyze the convergence properties of the consensus-alternating direction method of multipliers (ADMM) for solving general quadratically constrained quadratic programs. We prove…

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…

Off-Grid Direction-of-Arrival Estimation Using Second-Order Taylor Approximation

Huiping Huang, Hing Cheung So, Abdelhak M. Zoubir

The problem of off-grid direction-of-arrival (DOA) estimation is investigated. We develop a grid-based method to jointly estimate the closest spatial frequency (the sine of DOA) gr…
