A noise reduction method based on adaptive weighted symplectic geometry decomposition and its application in early gear fault diagnosis
TL;DR: An adaptive weighted symplectic geometry decomposition (AWSGD) method is proposed for noise reduction, which is adaptive without setting parameters manually and can avoid the defect of the traditional noise reduction method by energy size.

The $\alpha$ - $\mu$ Distribution: A Physical Fading Model for the Stacy Distribution
TL;DR: A fading model is introduced, which explores the nonlinearity of the propagation medium and derives the corresponding fading distribution-the alpha-mu distribution-which is in fact a rewritten form of the Stacy (generalized Gamma) distribution.
