Channel phase processing in wireless networks for human activity recognition
(Elsevier, 2023-12)
The phase of the channel state information (CSI) is underutilized as a source of information in wireless sensing due to its sensitivity to synchronization errors of the signal reception. A linear transformation of the phase ...
Empirical Doppler Characterization of Signals Scattered by Wind Turbines in the UHF Band under Near Field Condition
(Hindawi Publishing Corporation, 2013)
Time variability of the scattering signals from wind turbines may lead to degradation problems on the communication systems provided in the UHF band, especially under near field condition. In order to analyze the variability ...
Simplified Formulae for the Estimation of Offshore Wind Turbines Clutter on Marine Radars
(Hindawi Publishing, 2014)
The potential impact that offshore wind farms may cause on nearby marine radars should be considered before the wind farm is installed. Strong radar echoes from the turbines may degrade radars' detection capability in the ...
