URGLQ: An Efficient Covariance Matrix Reconstruction Method for Robust Adaptive Beamforming [PDF]
IEEE Transactions on Aerospace and Electronic Systems, 2023 The computational complexity of the conventional adaptive beamformer is relatively large, and the performance degrades significantly due to the model mismatch errors and the unwanted signals in received data. In this paper, an efficient unwanted signal removal and Gauss-Legendre quadrature (URGLQ)-based covariance matrix reconstruction method is ...

Augmented Covariance Matrix Reconstruction for DOA Estimation Using Difference Coarray
IEEE Transactions on Signal Processing, 2021As is well known, nonuniform linear arrays have significant advantages in array aperture and degrees of freedom over uniform linear arrays. Using their difference coarrays, subspace-based approaches can be utilized to perform underdetermined and high-resolution direction-of-arrival (DOA) estimation.

A Toeplitz Covariance Matrix Reconstruction Approach for Direction-of-Arrival Estimation
IEEE Transactions on Vehicular Technology, 2017It is known that there exist two kinds of methods for direction-of-arrival (DOA) estimation in the literature: the subspace-based method and the sparsity-based method. However, pervious works reveal that the former method cannot address the case in which the number of signals is larger than that of sensors, whereas the latter one always suffers from ...

Covariance Matrix Reconstruction of Nonclassical Light Generated On-Chip
Conference on Lasers and Electro-Optics, 2022We reconstruct covariance matrices of two-mode states generated in an above-threshold on-chip optical parametric oscillator. Up to 2.3 dB squeezing is directly observed and all quadratures are measured, as a function of pump intensity.
