Annual IEEE Communications Society Conference on Sensor, Mesh and Ad Hoc Communications and Networks, 2020
The Terahertz (0.1-10 THz) band is envisioned to meet the rapid growth of wireless data rates. Achieving high beamforming gain and reduced hardware complexity, the array-of-subarrays (AoSA) hybrid beamforming is a promising technology to be adopted for ...

Direction of Arrival (DoA) Estimation Using Irregular Arrays
2023 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting (USNC-URSI), 2023In this paper, a new method for DoA estimation using irregular synthetic array will be presented. Power spectral density (PSD) which helps to estimate DoA of multiple sources is computed over signals received by irregular arrays/trajectories.

Direction-of-Arrival (DOA) Estimation based on Spacetime-Modulated Metasurface
2019 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting, 2019We introduce the concept of DOA estimation based on spacetime-modulated 2D-patch-array metasurface. Such a system, compared to conventional DOA estimators, offers the key advantage of requiring only one receiving antenna, with the metasurface placed in ...

Coarray Tensor Direction-of-Arrival Estimation
IEEE Transactions on Signal Processing, 2023Augmented coarrays can be derived from spatially undersampled signals of sparse arrays for underdetermined direction-of-arrival (DOA) estimation. With the extended dimension of sparse arrays, the sampled signals can be modeled as sub-Nyquist tensors ...

An Off-Grid Iterative Reweighted Approach to One-Bit Direction of Arrival Estimation
IEEE Transactions on Vehicular Technology, 2023This article addresses the problem of direction of arrival (DOA) estimation only relying on the sign bits of the array signal. A new optimization model is formulated to realize the simultaneous estimation of one-bit DOAs and source number.
