Direction of arrival (DOA) estimation system using 3D printed Luneburg lens
2016 IEEE/ACES International Conference on Wireless Information Technology and Systems (ICWITS) and Applied Computational Electromagnetics (ACES), 2016A novel direction of arrival (DOA) estimation system based on a broadband 3D printed Luneburg lens is reported in this paper. Using the property of a Luneburg lens that the focus point of an incident plane wave is at the opposite side on the surface of the lens, 36 diode detectors with 10 degree spacing are mounted around the surface of a 3D printed ...

A SYSTOLIC ARCHITECTURE FOR CAPON'S DIRECTIONS-OF-ARRIVAL (DOA) ESTIMATION METHOD
Parallel Algorithms and Applications, 1993In this paper, a systolic array architecture is designed for the parallel implementation of Capon's direction-of-arrival estimation method in array signal processing. The architecture uses the QR decomposition on the data matrix to compute Capon's angular spectrum. The systolic array employs N(N + l)/2 + N processing elements (PEs).

Direction of Arrival (DOA) Estimation Using Electrically Small Tuned Dipole Antennas
IEEE Transactions on Antennas and Propagation, 2006We present a methodology for the direction of arrival (DOA) estimation using the induced voltages that are measured at the loads connected to electrically small tuned dipole antenna arrays illuminated by the signal of interest (SOI). The matrix pencil method is applied directly to the induced voltages to estimate the DOA of the various signals.

Direction of arrival (DOA) estimation with extended optimum co-prime sensor array (EOCSA)
Multidimensional Systems and Signal Processing, 2021In this study we propose a novel sparse antenna array and suitable beamforming algorithm in order to decrease the number of antennas in large-scale antenna systems (LSASs) and achieving the performance of a dense antenna array. To design a sparse array we use the familiar array geometry that is called co-prime sensor array (CSA), which has been ...

Comparative Study of Wideband Subspace Direction of Arrival (DOA) estimation methods
The Journal of the Acoustical Society of America, 2008Signal subspace Methods like ESPRIT, MUSIC and MATRIX PENCIL, provides high resolution Direction Of Arrival (DOA) estimation in comparison to traditional Delay and Sum and Capon methods, which are limited by sensor spacing. However underwater Acoustics signals are inherently wideband in nature and most of these Subspace methods works on narrowband ...

2020 17th Annual IEEE International Conference on Sensing, Communication, and Networking (SECON), 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 THz communications.
