The local polynomial Fourier transform (LPFT), as a high-order generalization of the short-
time Fourier transform (STFT), has been developed and used for many different applications …

Periodic signals can be decomposed into sets of sinusoids having frequencies that are
integer multiples of a fundamental frequency. The problem of finding such fundamental …

Exploiting the impulse-like nature of excitation in the sequence of glottal cycles, a method is
proposed to derive the instantaneous fundamental frequency from speech signals. The …

In this paper, a variational mode decomposition (VMD) based method has been proposed
for the instantaneous detection of voiced/non-voiced (V/NV) regions in the speech signals. In …

The analysis of speech of people with Parkinson's disease is an interesting and highly
relevant topic that has attracted the research community during several years. The advances …

The paper presents a pitch estimation technique based on the robust algorithm for pitch
tracking (RAPT) framework. The proposed solution provides estimation of instantaneous …

In this paper, we formulate the multi-pitch estimation problem and propose a number of
methods to estimate the set of fundamental frequencies. The proposed methods, based on …

In this paper, a novel approach is proposed to determine instantaneous fundamental
frequency (IFF) of speech signals. In the proposed method, the detected voiced speech …

We propose a robust event-based method for estimation of the instantaneous fundamental
frequency of a voiced speech signal. The amplitude and frequency modulated (AM-FM) …

We propose a novel and robust algorithm for antenna scan type (AST) recognition in
electronic warfare (EW). The stages of the algorithm are scan period estimation …
