Unsupervised Multiple Source Localization Using Relative Harmonic Coefficients
ICASSP 2020 - 2020 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2020This paper presents an unsupervised multi-source localization algorithm using a recently introduced feature called the relative harmonic coefficients. We derive a closed-form expression of the feature and briefly summarize its unique properties. We then exploit this feature to develop a single-source frame/bin detector which simplifies the challenging ...

Sound source localization using multiple circular microphone arrays based on harmonic analysis
The Journal of the Acoustical Society of America, 2021This paper proposes a multiple signal classification (MUSIC) framework for direction-of-arrival estimation by combining multiple circular arrays in the circular-harmonics domain. We jointly transform the received signals of all sub-arrays into the circular harmonics domain to generate a set of sound field coefficients containing the direction ...

Frequency estimation using multiple sources and multiple harmonic components
Proceedings of the 2002 American Control Conference (IEEE Cat. No.CH37301), 2003An algorithm similar to a phase-locked loop is proposed for the estimation of the frequency of a periodic signal. It is capable of using harmonic components for improved estimation performance. In a similar manner, multiple signals may also be combined in the algorithm, enabling the estimation of the frequency of a periodic source, given information ...

Localization and Characterization of Multiple Harmonic Sources
IEEE/ACM Transactions on Audio, Speech, and Language Processing, 2016We introduce a new and intuitive algorithm to characterize and localize multiple harmonic sources intersecting in the spatial and frequency domains. It jointly estimates their fundamental frequencies, their respective amplitudes, and their directions of arrival based on an intelligent non-parametric signal representation. To obtain these parameters, we

Multiple source localisation in the spherical harmonic domain
2014 14th International Workshop on Acoustic Signal Enhancement (IWAENC), 2014Spherical arrays facilitate processing and analysis of sound fields with the potential for high resolution in three dimensions in the spherical harmonic domain. Using the captured sound field, robust source localisation systems are required for speech acquisition, speaker tracking and environment mapping.

Determining the harmonic contributions of multiple harmonic sources using data clustering analysis
2015 International Symposium on Smart Electric Distribution Systems and Technologies (EDST), 2015A new method is proposed in this paper to determine the harmonic contributions of multiple harmonic sources with consideration of the fluctuation of the background harmonic voltage. Affinity propagation and k-means clustering are used for determining each cluster of the harmonic measurement data, and the harmonic contributions of multiple harmonic ...

Monitoring multiple harmonic sources in power systems using neural networks
2005 IEEE Russia Power Tech, 2005This paper presents a method for monitoring multiple harmonic sources in a power system using a reduced number of harmonic monitoring stations. Artificial neural networks are used to provide initial estimates of the harmonic sources based on the measured harmonics and fundamental load flows.

Optimum filter design for distribution feeders with multiple harmonic sources
Electric Power Systems Research, 1992Abstract A procedure is developed for selection and placement of optimum filters on distribution feeders that have distributed and balanced or unbalanced harmonic sources and variable compensating capacitors. The objective is to minimize voltage harmonic distortion for all buses on the feeder.
