Non-stationary noise power spectral density estimation based on regional statistics [PDF]
2016 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2016 Estimating the noise power spectral density (PSD) is essential for single channel speech enhancement algorithms. In this paper, we propose a noise PSD estimation approach based on regional statistics. The proposed regional statistics consist of four features representing the statistics of the past and present periodograms in a short-time period.

Gravitational-wave astronomy with an uncertain noise power spectral density [PDF]
Physical Review Research, 2020 In order to extract information about the properties of compact binaries, we must estimate the noise power spectral density of gravitational-wave data, which depends on the properties of the gravitational-wave detector. In practice, it is not possible to

Sensitivity of power spectral density techniques to numerical parameters in analyzing neutron noise experiments [PDF]
Progress in Nuclear Energy, 2017 Abstract Power spectral density (PSD) methods are well-known and widely used for the analysis of neutron noise experiments and obtaining the reactor's integral kinetic parameters, i.e., the effective delayed neutron fraction βeff and the prompt neutron generation time Λ .

Noise power spectral density estimation based on optimal smoothing and minimum statistics [PDF]
IEEE Transactions on Speech and Audio Processing, 2001 We describe a method to estimate the power spectral density of nonstationary noise when a noisy speech signal is given. The method can be combined with any speech enhancement algorithm which requires a noise power spectral density estimate. In contrast to other methods, our approach does not use a voice activity detector.

REACTOR NOISE ANALYSIS FOR A GRAPHITE-MODERATED AND -REFLECTED CORE IN KUCA [PDF]
EPJ Web of Conferences, 2021 In graphite-reflected thermal reactors, even a detector placed far from fuel region may detect a certain degree of the correlation amplitude. This is because mean free path of neutrons in graphite is longer than that in water or polyethylene.

Effects of Timing Noise on Square-Wave Optoelectronic Oscillators
Applied Sciences, 2021 Optoelectronic oscillators produce microwave-modulated optical beams without external modulation. The most commonly studied types produces narrow-band output, i.e., optical output modulated by a sinusoid, in which case phase noise determines key figures ...
