DTI denoising for data with low signal to noise ratios [PDF]
, 2005 Low signal to noise ratio (SNR) experiments in diffusion tensor imaging (DTI) give key information about tracking and anisotropy, e. g., by measurements with small voxel sizes or with high b values. However, due to the complicated and dominating impact of thermal noise such data are still seldom analysed.

Spatial Smoothing for Diffusion Tensor Imaging with low Signal to Noise Ratios [PDF]
, 2003 Though low signal to noise ratio (SNR) experiments in DTI give key information about tracking and anisotropy, e.g. by measurements with very small voxel sizes, due to the complicated impact of thermal noise such experiments are up to now seldom analysed.

Isotonic recalibration under a low signal-to-noise ratio
Scandinavian Actuarial Journal, 2023 Insurance pricing systems should fulfill the auto-calibration property to ensure that there is no systematic cross-financing between different price cohorts. Often, regression models are not auto-calibrated. We propose to apply isotonic recalibration to a given regression model to ensure auto-calibration.

Performance of binary block codes at low signal-to-noise ratios [PDF]
IEEE Transactions on Information Theory, 1992 Summary: The performance of general binary block codes on an unquantized additive white Gaussian noise (AWGN) channel at low signal-to-noise ratios is considered. Expressions are derived for both the block-error and the bit- error probabilities near the point where the bit signal-to-noise ratio is zero.

A systematic investigation of detectors for low signal-to-noise ratio EMG signals
F1000Research, 2023 Background Active participation of stroke survivors during robot-assisted movement therapy is essential for sensorimotor recovery. Robot-assisted therapy contingent on movement intention is an effective way to encourage patients’ active engagement. For severely impaired stroke patients with no residual movements, a surface electromyogram (EMG) has been

Selection Relaying at Low Signal to Noise Ratios
CoRR, 2007 Performance of cooperative diversity schemes at Low Signal to Noise Ratios (LSNR) was recently studied by Avestimehr et. al. [1] who emphasized the importance of diversity gain over multiplexing gain at low SNRs. It has also been pointed out that continuous energy transfer to the channel is necessary for achieving the max-flow min-cut bound at LSNR ...

Design of pulse laser high-precision ranging algorithm under low signal-to-noise ratio
Open Physics, 2022 Because the traditional pulse laser high-precision ranging method has the problems of low ranging accuracy and long ranging time, a pulse laser high-precision ranging algorithm under low signal-to-noise ratio is proposed.
