Analysis of Noise Coupling From a Power Distribution Network to Signal Traces in High-Speed Multilayer Printed Circuit Boards [PDF]

open access: yes, 2006
As layout density increases in highly integrated multilayer printed circuit boards (PCBs), the noise that exists in the power distribution network (PDN) is increasingly coupled to the signal traces, and precise modeling to describe the coupling ...

Low Frequency Noise Characterization and Signal-to-Noise Ratio Optimization for Silicon Hall Cross Sensors

open access: yesIEEE Journal of the Electron Devices Society, 2015
In this paper, silicon-based Hall cross sensors with different device dimensions and carrier densities are designed and fabricated. Low frequency noise behavior regarding to the device dimension and carrier density of the Hall cross sensors has been ...

DOA estimation algorithm based on spread spectrum sequence in low signal-to-noise ratio

open access: yesEURASIP Journal on Wireless Communications and Networking, 2022
Spread spectrum communication is a common communication method in underwater communication. Based on the space-time processor received by the array, it can filter the signals arriving along each path separately.

Matched subspace detection with hypothesis dependent noise power [PDF]

open access: yes, 2008
We consider the problem of detecting a subspace signal in white Gaussian noise when the noise power may be different under the null hypothesis—where it is assumed to be known—and the alternative hypothesis.

Time-Domain Anti-Interference Method for Ship Radiated Noise Signal

open access: yesEURASIP Journal on Advances in Signal Processing, 2022
Ship radiated noise signal is one of the important ways to detect and identify ships, and emission of interference noise to shield its own radiated noise signal is a common countermeasure.

Radar Target Detection Algorithm Using Convolutional Neural Network to Process Graphically Expressed Range Time Series Signals

open access: yesSensors, 2022
Under the condition of low signal-to-noise ratio, the target detection performance of radar decreases, which seriously affects the tracking and recognition for the long-range small targets.

Comparative signal-to-noise analysis of fibre-optic based optical coherence tomography systems [PDF]

open access: yes, 2005
Several optical coherence tomography ( OCT) systems are proposed using optical. fibre components and based around Fizeau sensing interferometers. The theoretical signal- to- noise ratio ( SNR) is calculated for each of the proposed configurations ...

Radar signals recognition based on attention and denoising residual network [PDF]

open access: yesITM Web of Conferences, 2022
To solve the problem that complex radar emitter signals are difficult to identify under low signal-to-noise ratio, this paper proposes a novel radar signal recognition method based on an improved deep residual network.

Stochastic resonance in electrical circuits—I: Conventional stochastic resonance. [PDF]

open access: yes, 1999
Stochastic resonance (SR), a phenomenon in which a periodic signal in a nonlinear system can be amplified by added noise, is introduced and discussed. Techniques for investigating SR using electronic circuits are described in practical terms.

Signal-to-noise ratio (SNR) evaluation.

open access: yes, 2022
Mean signal intensity was calculated by averaging the region of interest’s (ROI) pixels’ intensities (Gd-DOTA concentration 5.1 mM). Square ROIs were fitted into each of the contrast filled phantoms (1–6), circular ROIs were horizontally positioned in ...
