Theoretical and experimental analysis of phase noise in semiconductor lasers biased below threshold

JPhys Photonics
We report a theoretical and experimental study of phase noise in semiconductor lasers when the bias current is below the threshold value. The theoretical study is performed by using two types of rate equations, with additive and multiplicative noise ...

Anisotropic Diffusion Based Multiplicative Speckle Noise Removal

Sensors, 2019
Multiplicative speckle noise removal is a challenging task in image processing. Motivated by the performance of anisotropic diffusion in additive noise removal and the structure of the standard deviation of a compressed speckle noisy image, we address ...

Sigma-Point Particle Filter for Parameter Estimation in a Multiplicative Noise Environment

Journal of Advances in Modeling Earth Systems, 2011
A pre-requisite for the “optimal estimate” by the ensemble-based Kalman filter (EnKF) is the Gaussian assumption for background and observation errors, which is often violated when the errors are multiplicative, even for a linear system. This study first
