Localization Coverage Analysis of THz Communication Systems with a 3D Array
Pinjun Zheng, Tarig Ballal, Hui Chen +2
This paper considers the problem of estimating the position and orientation of a user equipped with a three-dimensional (3D) array receiving downlink far-field THz signals from mul…
Antenna Selection in Switch-Based MIMO Arrays via DOA threshold region Approximation
Hui Chen, Tarig Ballal, Mohammed E. Eltayeb +1
Direction-of-arrival (DOA) information is vital for multiple-input-multiple-output (MIMO) systems to complete localization and beamforming tasks. Switched antenna arrays have recen…
Instantaneous GNSS Ambiguity Resolution and Attitude Determination via Riemannian Manifold Optimization
Xing Liu, Tarig Ballal, Mohanad Ahmed +1
We present an ambiguity resolution method for Global Navigation Satellite System (GNSS)-based attitude determination. A GNSS attitude model with nonlinear constraints is used to ri…
Portfolio Optimization Using a Consistent Vector-Based MSE Estimation Approach
Maaz Mahadi, Tarig Ballal, Muhammad Moinuddin +2
This paper is concerned with optimizing the global minimum-variance portfolio's (GMVP) weights in high-dimensional settings where both observation and population dimensions grow at…
Details Preserving Deep Collaborative Filtering-Based Method for Image Denoising
Basit O. Alawode, Mudassir Masood, Tarig Ballal +1
In spite of the improvements achieved by the several denoising algorithms over the years, many of them still fail at preserving the fine details of the image after denoising. This…
Collaborative Filtering-Based Method for Low-Resolution and Details Preserving Image Denoising
Basit O. Alawode, Mudassir Masood, Tarig Ballal +1
Over the years, progressive improvements in denoising performance have been achieved by several image denoising algorithms that have been proposed. Despite this, many of these stat…
