An APG-MUSIC Algorithm Based-on Optimized Sampling Array
MATEC Web of Conferences, 2018 This paper proposes a novel two-dimensional direction of arrival (2D-DOA) estimation with optimized sparse sampling array, which is combined with Accelerated Proximal Gradient singular value thresholding(APG) and Multiple Signal Classification(MUSIC ...

Political Partisanship and State‐Level Bank Efficiency
Financial Review, EarlyView.ABSTRACT We examine the relationship between political partisanship and commercial bank efficiency in the United States from 1972 to 2020, assessing the persistent influence of political affiliations at the state and District of Columbia levels. Bank efficiency scores are estimated using a double‐bootstrap approach, and the analysis is conducted within

Performance evaluation of direction-of-arrival (DOA) estimation algorithms for mobile communication systems [PDF]
VTC2000-Spring. 2000 IEEE 51st Vehicular Technology Conference Proceedings (Cat. No.00CH37026), 2002 Spatial filtering for mobile communications has attracted a lot of attention over the last decade and is currently considered a very promising technique that will help future cellular networks achieve their ambitious goals. One way to accomplish this is via array signal processing with algorithms which estimate the direction-of-arrival (DOA) of the ...

Intelligent Acousto‐Electrical Metamaterials (IAM) for Sound Source Detection
Advanced Materials, Volume 38, Issue 36, 26 June 2026.Our proposed metamaterial concept enables sound source detection using a single material, in contrast to conventional arrays that require dozens or even hundreds of transducers. We show that the coupled acoustic–vibrational–electrical responses in piezoelectric metamaterials give rise to topology‐governed charge transport, producing distinct voltage ...

Adaptive Based Beamforming for Direction-of- Arrival (DOA) Estimation
CVR Journal of Science & Technology, 2015 Nowadays mobile users require increased coverage, quality of service and capacity in wireless communications. By using adaptive antennas at both transmitter and receiver in wireless communication, we can easily reach the required improvement. In this paper Adaptive Antenna plays a major role to improve the performance of wireless communication systems.
