PSD Estimation and Source Separation in a Noisy Reverberant Environment using a Spherical Microphone Array

Fahim, Abdullah; Samarasinghe, Prasanga; Abhayapala, Thushara


In this paper, we propose an efficient technique for estimating individual power spectral density (PSD) components, i.e., PSD of each desired sound source as well as of noise and reverberation, in a multi-source reverberant sound scene with coherent background noise. We formulate the problem in the spherical harmonics domain to take the advantage of the inherent orthogonality of the spherical harmonics basis functions and extract the PSD components from the cross-correlation between the...[Show more]
