New Designs on MVDR Robust Adaptive Beamforming Based on Optimal Steering Vector Estimation
Yongwei Huang, Mingkang Zhou, Sergiy A. Vorobyov
The robust adaptive beamforming design problem based on estimation of the signal of interest steering vector is considered in the paper. In this case, the optimal beamformer is obt…
Joint Detection and Localization of an Unknown Number of Sources Using Algebraic Structure of the Noise Subspace
Matthew W. Morency, Sergiy A. Vorobyov, Geert Leus
Source localization and spectral estimation are among the most fundamental problems in statistical and array signal processing. Methods which rely on the orthogonality of the signa…
An Inner SOCP Approximate Algorithm for Robust Adaptive Beamforming for General-Rank Signal Model
Yongwei Huang, Sergiy A. Vorobyov
The worst-case robust adaptive beamforming problem for general-rank signal model is considered. Its formulation is to maximize the worst-case signal-to-interference-plus-noise rati…
Covariance Matrix Estimation for Massive MIMO
Karthik Upadhya, Sergiy A. Vorobyov
We propose a novel pilot structure for covariance matrix estimation in massive multiple-input multiple-output (MIMO) systems in which each user transmits two pilot sequences, with…
An axially-variant kernel imaging model applied to ultrasound image reconstruction
Mihai I. Florea, Adrian Basarab, Denis Kouamé +1
Existing ultrasound deconvolution approaches unrealistically assume, primarily for computational reasons, that the convolution model relies on a spatially invariant kernel and circ…
