Abstract: Estimation of the noise power spectral density (PSD) plays a critical role in most existing single-channel speech enhancement algorithms. In this paper, we present a novel noise PSD tracking algorithm, which employs a log-spectral power… read more here.

DOI: 10.1109/lcsys.2022.3178142
Abstract: We analyze a class of high-frequency, high-amplitude oscillatory systems in which periodicity occurs on two distinct time scales and establish the convergence of its trajectories to a suitably averaged system by recursively applying higher-order averaging.… read more here.
