Time-frequency structured decorrelation of speech signals via nonseparable Gabor frames

Abstract

We present a new approach to the linear representation of speech signals that combines desirable structure, computational e ciency and almost decorrelation. The basic principle is a statistically adapted, group{theoretical modi cation of the classical Gabor expansion. In contrast to traditional linear time{frequency (TF) representations which always… (More)
