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…
