Convex Estimation of Sparse-Smooth Power Spectral Densities from Mixtures of Realizations with Application to Weather Radar
Hiroki Kuroda, Daichi Kitahara, Eiichi Yoshikawa +2
In this paper, we propose a convex optimization-based estimation of sparse and smooth power spectral densities (PSDs) of complex-valued random processes from mixtures of realizatio…

Frequency-Undersampled Short-Time Fourier Transform
Daichi Kitahara
The short-time Fourier transform (STFT) usually computes the same number of frequency components as the frame length while overlapping adjacent time frames by more than half. As a…
