Separation of Multicomponent Micro-Doppler Signal with Missing Samples

Remote Sensing
The problem of separating multicomponent micro-Doppler (m-D) signals is common in the field of radar signal processing. In some implementations, it is necessary to separate the multicomponent m-D signal that contains missing samples.

A TC-Based Multicomponent LFM Signal Characterization Method Under Impulsive Noise and Its Application

IET Signal Processing
The burst-like and high-amplitude characteristics of impulsive noise, which markedly differ from those of Gaussian noise, render methods based on the Gaussian assumption unable to accurately characterize signals under impulsive noise.

Phosphorelays provide tunable signal processing capabilities for the cell [PDF]

, 2013
Achieving a complete understanding of cellular signal transduction requires deciphering the relation between structural and biochemical features of a signaling system and the shape of the signal-response relationship it embeds.

The face is central to primate multicomponent signals [PDF]

International Journal of Primatology, 2022
AbstractA wealth of experimental and observational evidence suggests that faces have become increasingly important in the communication system of primates over evolutionary time and that both the static and moveable aspects of faces convey considerable information. Therefore, whenever there is a visual component to any multicomponent signal the face is

Diffusion weighted image denoising using overcomplete local PCA. [PDF]

PLoS ONE, 2013
Diffusion Weighted Images (DWI) normally shows a low Signal to Noise Ratio (SNR) due to the presence of noise from the measurement process that complicates and biases the estimation of quantitative diffusion parameters.

Compensation for High-Frequency Vibration of SAR Imaging in the Terahertz Band Based on Linear Chirplet Transform and Empirical Mode Decomposition

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
SAR in THz band is very important and valuable in the field of radar signal processing, and it is much sensitive to the high-frequency vibration of the platform due to the short wavelength.
