Dynamic Cell Division for Interference Management in Satellite Direct‐to‐Cell Systems

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT Direct‐to‐cell (D2C) connectivity enables future non‐terrestrial networks to provide service directly to standard terrestrial user equipment (UE) when terrestrial networks (TN) are unavailable. In this work, the satellite system is considered as a secondary network that supplements existing TN coverage while minimizing interference to the ...

Adaptive beamforming assisted receiver

, 2007
Adaptive beamforming is capable of separating user signals transmitted on the same carrier frequency, and thus provides a practical means of supporting multiusers in a space-division multiple-access scenario.

WAH‐i: Optimising microphone array geometry for customised localisation accuracy

Methods in Ecology and Evolution, EarlyView.
Abstract Accurate spatial localisation of free‐flying echolocating bats is foundational for resolving fine‐scale flight and echolocation behaviour, prey interception and spatial decision‐making in natural environments. Acoustic localisation using microphone arrays is widely employed for this purpose, yet array geometries in field studies are typically ...

Recent Advances in Microstrip Patch Antenna Optimization: Methods, Design Targets, and Emerging Trends

Applied Research, Volume 5, Issue 5, October 2026.
This systematic review synthesizes recent advances in Microstrip patch antennas (MPAs) optimization research, highlighting key design targets, optimization methodologies, performance trade‐offs, and application trends. The results demonstrate that MPA optimization is an inherently multivariable problem, with trade‐offs among antenna size, impedance ...

Delivery and Attitude Modulate Shared Neural Processing of Speech Through Distinct Frequency Channels

Psychophysiology, Volume 63, Issue 10, October 2026.
ABSTRACT Listeners' brains align when they attend to the same speech, but what determines how strongly they align is not well understood. We asked whether that alignment tracks the communicative relation between a listener and a message, manipulating it from the speaker's side and from the listener's, and bounding the account with a manipulation that ...

Model-Switched Beamformer with Large Dynamic Range

International Journal of Antennas and Propagation, 2014
The strong desired signal will be mitigated due to “self-nulling” for the adaptive beamformer, even if the array calibration is used. The proposed methodology switches the models between phased array and adaptive array.

Fault‐Controlled Plumbing System Beneath Lipari Volcanic Island Revealed by Seismic Matrix Imaging

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Lipari Island hosts an active magmatic–hydrothermal system, but its deep plumbing architecture remains poorly resolved due to strong seismic scattering. We apply passive seismic matrix imaging to public vertical‐component cross‐correlation functions from the dense 2018 Lipari nodal array, recovering relative‐reflectivity structures to ∼10 km ...

Radio‐Frequency Front‐End‐Free Hybrid Code‐Division and Space‐Division Wireless Multiplexing Using Space‐Time‐Coding Metasurface

Nanophotonics, Volume 15, Issue 17, 11 September 2026.
This work constructs a radio‐frequency front‐end‐free hybrid code‐division and space‐division‐multiplexing wireless communication system built on programmable space‐time‐coding metasurfaces. Orthogonal pseudo‐random codes reliably separate overlapped multistream signals that share identical frequency, time, and spatial resources.
