This paper addresses the problem of noise reduction in the time domain where the clean speech sample at every time instant is estimated by filtering a vector of the noisy speech signal. Such a clean speech estimate consists of both the filtered speech and residual noise (filtered noise) as the...
Time-domain noise suppression A process for noise reduction during the transmission of acoustic useful signals includes the following steps of: (a) determining when a speech pause is present; (b) branching the incoming TC signal from the main signal path and utilizin... M Walker - US 被引量...

Phase-sensitive optical time domain reflectometry (φOTDR) is a simple and effective tool allowing the distributed monitoring of vibrations along single-mode fibers. Up to now, φOTDRs have been used mostly for the measurement of sub-kHz vibrations, normally in the context of intrusion sensing. ...
In this paper, a novel approach is proposed for fading noise reduction in phase interrogation based phase-sensitive optical time domain reflectometry (Φ-OTDR), which utilizes multi-wavelength optical pulses as the probe. Theoretical analysis is performed on the interference signal that is comprised ...
Title: Comparison of Time-Domain and Frequency-Domain Phase Noise Analyses Abstract approved: Kartikeya Mayaram Un-Ku Moon This thesis presents a comparison of time-domain and frequency-domain algorithms for phase noise calculation in oscillators. Floquet theory provides the mathematical foundation for ...
Here we firstly define the fft noise function in brief , a Fast Fourier transform (FFT) is an algorithm that computes the discrete Fourier transform (DFT) of a sequence, or its inverse (IDFT). Fourier analysis converts a signal from its original domain (often time or space) to a represen...
