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…

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 λ/2. This problem in direction of arrival (DOA) estimation and can be solved by d…
