In this work, we propose an alternating low-rank decomposition (ALRD) approach and novel subspace algorithms for direction-of-arrival (DOA) estimation. In the ALRD scheme, the …
The issue of asset tracking in dense environments where the performance of the global positioning system (GPS) becomes unavailable or unreliable is addressed. The proposed …

Several algorithms for direction-of-arrival (DOA) estimation with uniform circular arrays rely on the beamspace transform as it allows computationally efficient estimation of the angles-of …
C Liang, M Liu, Y Li, Y Wang, X Hu - Remote Sensing, 2024 - mdpi.com
In this paper, we explore the problem of direction-of-arrival (DOA) estimation for a non- uniform linear array (NULA) under strong noise. The compressed sensing (CS)-based …
In this paper, we consider the problem of low dimensional signal subspace estimation in a Bayesian context. We focus on compound Gaussian signals embedded in white Gaussian …
In the light of recent developments in optimal real L 1-norm principal-component analysis (PCA), we provide the first algorithm in the literature to carry out L 1-PCA of complex-valued …
