Abstract
In this paper, we study the inverse short-time Fourier transform (STFT). We propose a new vector formulation of STFT. We derive a family of inverse STFT estimators and a least squares one. We discuss their relationship and compare their performance with respect to both additive and multiplicative modifications to STFT. The influence of window, overlap, and zero-padding are investigated as well.
