On parameter estimation of symmetric alpha-stable distribution

Mohammadreza Hassannejad Bibalan, Hamidreza Amindavar

ICASSP 2016accepted

In this paper, a novel approach has been proposed for estimating the parameters of symmetric alpha-stable distribution with 1 ≤ α ≤ 2. Alpha-stable distribution can model the statistical behavior of non-Gaussian heavy tailed signals and noises with impulsive components. There are some serious consid…

A new alpha and gamma based mixture approximation for heavy-tailed Rayleigh distribution

Mohammadreza Hassannejad Bibalan, Hamidreza Amindavar

ICASSP 2015accepted

In this paper, a novel bi-parameter mixture approximation for modeling the statistical properties of heavy-tailed Rayleigh distribution is developed. Heavy-tailed Rayleigh distribution is basically the amplitude PDF of bi-variate isotropic α-stable distribution which appears in the envelope distribu…
