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…
Constrained Wrapped Least Squares: A Tool for High Accuracy GNSS Attitude Determination
Xing Liu, Tarig Ballal, Hui Chen +1
Attitude determination is a popular application of Global Navigation Satellite Systems (GNSS). Many methods have been developed to solve the attitude determination problem with dif…
A Tutorial on Terahertz-Band Localization for 6G Communication Systems
Hui Chen, Hadi Sarieddeen, Tarig Ballal +3
Terahertz (THz) communications are celebrated as key enablers for converged localization and sensing in future sixth-generation (6G) wireless communication systems and beyond. Inst…
TeraMIMO: A Channel Simulator for Wideband Ultra-Massive MIMO Terahertz Communications
Simon Tarboush, Hadi Sarieddeen, Hui Chen +4
Following recent advances in terahertz (THz) technology, there is a consensus on the crucial role of THz communications in the next generation of wireless systems. Aiming at cataly…
DOA Estimation with Non-Uniform Linear Arrays: A Phase-Difference Projection Approach
Hui Chen, Tarig Ballal, Tareq Y. Al-Naffouri
Phase wrapping is a major problem in direction-of-arrival (DOA) estimation using phase-difference observations. For a sensor pair with an inter-sensor spacing greater than half of…
A Derivation of Identifiable Condition for Non-Uniform Linear Array DOA Estimation
Hui Chen, Tarig Ballal, Tareq Y. Al-Naffouri
Phase ambiguity happens in uniform linear arrays (ULAs) when the sensor distance is greater than . This problem in direction of arrival (DOA) estimation and can be solved by d…
A Fast HRRP Synthesis Algorithm with Sensing Dictionary in GTD Model
Rong Fan, Qun Wan, Xiao Zhang +2
To achieve high range resolution profile (HRRP), the geometric theory of diffraction (GTD) parametric model is widely used in stepped-frequency radar system. In the paper, a fast s…
Complex Orthogonal Matching Pursuit and Its Exact Recovery Conditions
Rong Fan, Qun Wan, Yipeng Liu +2
In this paper, we present new results on using orthogonal matching pursuit (OMP), to solve the sparse approximation problem over redundant dictionaries for complex cases (i.e., com…
