Joint Estimation of Common-Slope Decay Rates and Spatial Amplitudes Using Parameterized Nonnegative Matrix Factorization
Jeremy B. Bai, Filip Elvander, Sebastian J. Schlecht
We formulate joint estimation of common-slope decay rates and amplitudes from room impulse responses (RIRs) as parameterized nonnegative matrix factorization with the Itakura--Sait…
Sound Field Estimation Using Optimal Transport Barycenters in the Presence of Phase Errors
Yuyang Liu, Johan Karlsson, Filip Elvander
This study introduces a novel approach for estimating plane-wave coefficients in sound field reconstruction, specifically addressing challenges posed by error-in-variable phase per…
Quantifying and Computing Covariance Uncertainty
Filip Elvander, Johan Karlsson, Toon van Waterschoot
In this work, we consider the problem of bounding the values of a covariance function corresponding to a continuous-time stationary stochastic process or signal. Specifically, for…
Mixed-Spectrum Signals -- Discrete Approximations and Variance Expressions for Covariance Estimates
Filip Elvander, Johan Karlsson
The estimation of the covariance function of a stochastic process, or signal, is of integral importance for a multitude of signal processing applications. In this work, we derive c…
