A Modified Minimum Statistics Algorithm for Reducing Time Varying Harmonic Noise
نویسندگان
چکیده
In this paper, a single-channel speech enhancement system is presented that is capable of reducing (time-varying) harmonic noise. For this, the well-known Minimum Statistics approach is modified in order to track and suppress the harmonic noise based on the harmonics’ fundamental frequency which is assumed to be known a priori. The performance of the proposed noise suppression system is shown to be consistently better than conventional approaches.

Design and Implementation of a Kalman Filter-Based Time-Varying Harmonics Analyzer
Nowadays with increasing use of numerous nonlinear loads, voltage and current harmonics in power systems are one of the most important problems power engineers encounter. Many of these nonlinear loads, because of their dynamic natures, inject time-varying harmonics into power system. Common techniques applied for harmonics measurement and assessment such as FFT have significant errors in presen...
متن کاملDual Channel Reduction of Rapidly Varying Harmonic and Random Noise Using a Spot Microphone
This contribution presents a dual channel speech enhancement system that is operating in the frequency domain. State-of-the-art estimators usually rely on the assumption that the noise signal is stationary or only slightly time-varying. In this contribution we are explicitly considering rapidly time-varying harmonic noise (e.g., engine noise). Therefore we take a spot microphone into account en...

This paper aims to investigate performance analysis and enhancements for the adaptive algorithms in speech enhancement and develop refined algorithms. The speech signal may get corrupted due to different types of noise. Hence, it becomes a challenge to maintain its high quality [2]. Noise Cancellation is a technique used for reducing undesired noise signal. Communication has become an integral ...

Fuzzy segmentation is an effective way of segmenting out objects in images containing both random noise and varying illumination. In this paper, a modified method based on the Comprehensive Learning Particle Swarm Optimization (CLPSO) is proposed for pixel classification in HSI color space by selecting a fuzzy classification system with minimum number of fuzzy rules and minimum number of incorr...
متن کاملDecision Feedback Sequence Estimation For Unwhitened ISI Channels With Applications To Multiuser Det - Selected Areas in Communications, IEEE Journal on
Decision feedback sequence estimation (DFSE), which is a reduced-complexity alternative to maximum likelihood sequence estimation (MLSE), can be used effectively for equalization of intersymbol interference (ISI) as well as for multiuser detection. The algorithm performs very well for whitened (minimum-phase) channels. For nonminimumphase channels, however, the algorithm is not very effective. ...
