On Guessing Random Additive Noise Decoding [PDF]
2024 IEEE International Symposium on Information Theory (ISIT)We revisit guessing random additive noise decoding (GRAND) in discrete additive noise channels. We derive a non-asymptotic random coding bound using elementary tools, which is applicable to arbitrary noise guessing orders. We then use this bound to analyze a universal variant of GRAND, that does not require knowledge of the noise distribution, and show

Rivers under Additive Noise [PDF]
Journal of Dynamics and Differential EquationsAbstract We consider the deterministic and stochastic versions of a first order non-autonomous differential equation which allows us to discuss the persistence of rivers (“fleuves”) under additive noise.

Additive Noise-Induced System Evolution (ANISE) [PDF]
Frontiers in Applied Mathematics and Statistics, 2022 Additive noise has been known for a long time to not change a systems stability. The discovery of stochastic and coherence resonance in nature and their analytical description has started to change this view in the last decades.

Fast additive noise steganalysis
SPIE Proceedings, 2004 This work reduces the computational requirements of the additive noise steganalysis presented by Harmsen and Pearlman. The additive noise model assumes that the stegoimage is created by adding a pseudo-noise to a coverimage. This addition predictably alters the joint histogram of the image.

The porosity of additive noise sequences [PDF]
2012 IEEE International Symposium on Information Theory Proceedings, 2012 Consider a binary additive noise channel with noiseless feedback. When the noise is a stationary and ergodic process $\mathbf{Z}$, the capacity is $1-\mathbb{H}(\mathbf{Z})$ ($\mathbb{H}(\cdot)$ denoting the entropy rate). It is shown analogously that when the noise is a deterministic sequence $z^\infty$, the capacity under finite-state encoding and ...

An Additive Approximation to Multiplicative Noise [PDF]
Journal of Mathematical Imaging and Vision, 2020 Multiplicative noise models are often used instead of additive noise models in cases in which the noise variance depends on the state. Furthermore, when Poisson distributions with relatively small counts are approximated with normal distributions, multiplicative noise approximations are straightforward to implement. There are a number of limitations in

Cramer–Rao lower bounds for change points in additive and multiplicative noise [PDF]
, 2004 The paper addresses the problem of determining the Cramer–Rao lower bounds (CRLBs) for noise and change-point parameters, for steplike signals corrupted by multiplicative and/or additive white noise. Closed-form expressions for the signal and noise CRLBs

Effects of Additive Noise in Binaural Rendering of Spherical Microphone Array Signals
, 2021 Additive noise produced by the recording hardware will contribute to streamed signals from spherical microphone arrays under practical conditions. For the application of binaural reproduction and under the assumption that the noise is uncorrelated ...

Time-scale analysis of abrupt changes corrupted by multiplicative noise [PDF]
, 2000 Multiplicative Abrupt Changes (ACs) have been considered in many applications. These applications include image processing (speckle) and random communication models (fading).
