Joint estimation of RETF vector and power spectral densities for speech enhancement based on alternating least squares
The multi-channel Wiener filter (MWF) is a well-known multi-microphone speech enhancement technique, aiming at improving the quality of the recorded speech signals in noisy and reverberant environments. Assuming that reverberation and ambient noise can be ...
2019Multi-triplet bound states and finite-temperature dynamics in highly frustrated quantum spin ladders
Low-dimensional quantum magnets at finite temperatures present a complex interplay of quantum and thermal fluctuation effects in a restricted phase space. While some information about dynamical response functions is available from theoretical studies of th ...
2016Phase AutoCorrelation (PAC) features for noise robust speech recognition
Hynek Hermansky, Hemant Misra, Shajith Ikbal
In this paper, we introduce a new class of noise robust features derived from an alternative measure of autocorrelation representing the phase variation of speech signal frame over time. These features, referred to as Phase AutoCorrelation (PAC) features i ...
2012Scaling properties and spatial organization of snow depth fields in sub-alpine forest and alpine tundra
This paper reports on a study analysing the spatial distribution functions, the correlation structures, and the power spectral densities of high-resolution LIDAR snow depths (∼1 m) in two adjacent 500 m × 500 m areas in the Colorado Rocky Mountains, one a ...
Wiley-Blackwell2009A new technique for high-resolution frequency domain optical coherence tomography
Frequency domain optical coherence tomography (FDOCT) is a new technique that is well-suited for fast imaging of biological specimens, as well as non-biological objects. The measurements are in the frequency domain, and the objective is to retrieve an arti ...

Spatially resolved photoluminescence spectra of thin GaAs quantum wells are measured by near-field spectroscopy, and two-energy autocorrelation functions of the spectra are derived. We demonstrate distinctly different autocorrelation functions for a 3-nm-t ...
