Additive White Gaussian Noise Level Estimation in SVD Domain for Images
IEEE Transactions on Image Processing, 2013 Accurate estimation of Gaussian noise level is of fundamental interest in a wide variety of vision and image processing applications as it is critical to the processing techniques that follow. In this paper, a new effective noise level estimation method is proposed on the basis of the study of singular values of noise-corrupted images.

Robust Parametric Modeling of Speech in Additive White Gaussian Noise
Journal of Signal and Information Processing, 2015 In estimating the linear prediction coefficients for an autoregressive spectral model, the concept of using the Yule-Walker equations is often invoked. In case of additive white Gaussian noise (AWGN), a typical parameter compensation method involves using a minimal set of Yule-Walker equation evaluations and removing a noise variance estimate from the ...

Optimal Tracking Performance of MIMO Discrete-Time Systems with Network Parameters
Discrete Dynamics in Nature and Society, 2016 The optimal regulation properties of multi-input and multioutput (MIMO) discrete-time networked control systems (NCSs), over additive white Gaussian noise (AWGN) fading channels, based on state space representation, are investigated.

Convexity of the Capacity of One-Bit Quantized Additive White Gaussian Noise Channels
Mathematics, 2022 In this study, the maximum error-free transmission rate of an additive white Gaussian noise channel with a symmetric analog-to-digital converter (ADC) was derived as a composite function of the binary entropy function, Gaussian Q-function, and the square

Noise suppression in inverse weak value based phase detection [PDF]
, 2017 We examine the effect of different sources of technical noise on inverse weak value-based precision phase measurements. We find that this type of measurement is similarly robust to technical noise as related experiments in the weak value regime.

A New Method for Building Low-Density-Parity-Check Codes
International Journal of Technology, 2019 This paper proposes a new method for building low-density-parity-check codes, exempt of cycle of length 4, based on a circulant permutation matrix, which needs very little memory for storage it in the encoder and a dual diagonal structure is applied ...
