Noise robust voice detector for speaker recognition
The effect of additive noise in a speaker recognition system is well known to be a crucial problem in real life applications. In a speaker recognition system, if the test utteranc...

Sampling-rate-aware noise generation
In this paper we consider the generation of discrete white noise. Despite this seems to be a simple problem, common noise generator implementations do not deliver comparable resul...

Source number estimation in impulsive noise environments using bootstrap techniques and robust statistics
We consider the problem of source number estimation in array processing when impulsive noise is present. To combat impulsive noise more effectively, two robust estimators with hig...

Joint Bayesian removal of impulse and background noise
We present a method for the removal of noise including nonGaussian impulses from a signal. Impulse noise is removed jointly a homogenous Gaussian noise floor using a Gabor regres...

Frequency-aware PPV: a robust phase macromodel for accurate oscillator noise analysis
— Perturbation Projection Vector (PPV) is an established technique for oscillator phase noise analysis; However, the PPV method significantly loses accuracy when circuits have l...
