Gaussian Signal Detection With Product Arrays
IEEE Access, 2020 The paper specifies the probability density function (PDF) for the detection statistic for a product processor of colinear arrays. The product processor's detection PDF is a scaled product of the detection statistic with modified Bessel functions.

The sparse array elements selection in sparse imaging of circular-array photoacoustic tomography
Journal of Innovative Optical Health Sciences, 2022 Photoacoustic imaging (PAI) has been developed, and photoacoustic computed tomography (PACT) is widely used for in vivo tissue and mouse imaging. Simulated annealing (SA) algorithm solves optimization problems, and compressed sensing (CS) recovers sparse signals from undersampled measurements. We aim to develop an advanced sparse imaging framework for

Sparse Billboard and T-Shaped Arrays for Two-Dimensional Direction of Arrival Estimation
IEEE Open Journal of Signal Processing, 2023 In two-dimensional direction of arrival (2D-DOA) estimation, planar arrays can estimate the elevation and azimuth angles simultaneously. However, many planar array topologies such as billboard, L-shaped, T-shaped, and 2D nested arrays suffer from mutual ...

Evaluating Spatial Resolution and Channel Capacity of Sparse Cylindrical Arrays for Massive MIMO
IEEE Access, 2017 How to design antenna arrays plays an important role in wireless communications, especially when there are hundreds of antennas. In massive multiple-input and multiple-output (MIMO), if the number of antennas and RF chains are increasing, the channel ...
