Distractor suppression leads to reduced flanker interference [PDF]

Attention, Perception, & Psychophysics, 2020
AbstractRecent studies using the additional singleton paradigm have shown that regularities in distractor locations can cause biases in the spatial priority map, such that attentional capture by salient singletons is reduced for locations that are likely to contain distractors.

On Phase Noise Suppression in Full-Duplex Systems [PDF]

, 2014
Oscillator phase noise has been shown to be one of the main performance limiting factors in full-duplex systems. In this paper, we consider the problem of self-interference cancellation with phase noise suppression in full-duplex systems. The feasibility

Active Blanket Jamming Suppression Method for Spaceborne SAR Images Based on Regional Feature Refinement Perceptual Learning

Leida xuebao
Spaceborne Synthetic Aperture Radar (SAR) systems are often subject to strong electromagnetic interference, resulting in imaging quality degradation. However, existing image domain-based interference suppression methods are prone to image distortion and ...

CARNet: An effective method for SAR image interference suppression

International Journal of Applied Earth Observations and Geoinformation, 2022
Synthetic aperture radar (SAR) routinely confronts the interference of radiofrequency devices in normal missions, causing ineffective imaging and seriously affecting Earth observation capability. In general, it is a great challenge to ensure interference

Dark state suppression and narrow fluorescent feature in a laser-driven lambda atom

, 2002
We discuss quantum interference effects in a three-level atom in lambda-configuration, where both transitions from the upper state to the lower states are driven by a single monochromatic laser field.

Molecular effects in the ionization of N$_2$, O$_2$ and F$_2$ by intense laser fields [PDF]

, 2004
In this paper we study the response in time of N$_2$, O$_2$ and F$_2$ to laser pulses having a wavelength of 390nm. We find single ionization suppression in O$_2$ and its absence in F$_2$, in accordance with experimental results at $\lambda = 800$nm ...

Inter-tier Interference Suppression in Heterogeneous Cloud Radio Access Networks

, 2015
Incorporating cloud computing into heterogeneous networks, the heterogeneous cloud radio access network (H-CRAN) has been proposed as a promising paradigm to enhance both spectral and energy efficiencies. Developing interference suppression strategies is

A PELT-KCN Algorithm for FMCW Radar Interference Suppression Based on Signal Reconstruction

IEEE Access, 2020
In frequency-modulated continuous-wave (FMCW) radar interference suppression based on signal reconstruction, the pruned exact linear time (PELT) algorithm is used to detect the time positions of the interference.

Saturated Interference in SAR: Theoretical Analysis and Suppression Solutions

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Synthetic aperture radar (SAR) systems are highly sensitive to interference, making interference suppression a critical concern. While significant research has been conducted on SAR interference suppression using parametric, nonparametric, semiparametric
