Special Issue Information
Dear Colleagues,
The goal of time–frequency analysis is to represent a signal in a domain that allows for the simultaneous description of the temporal and spectral characteristics of that signal. However, the problem of time–frequency representation is generally not uniquely solvable due to being under-constrained, providing few general mathematical constraints and allowing for infinite degrees of freedom. Historically, this has led to many different approaches to signal representation. For instance, short-time Fourier transform (STFT) and other time–frequency distributions and time-scale methods have long been staples of time–frequency analysis. In recent years, AM-FM models and adaptive mode decompositions have made further advances in modeling signals with non-stationary frequency components, and several new developments in time–frequency reassignment and synchrosqueezing methods have been made.
This Special Issue aims to offer researchers the opportunity to share their original work and ideas around time–frequency analysis through papers providing theoretical insights, recent mathematical advances, and the latest applications of techniques in this field for solving various problems. Additionally, works that utilize entropy-based methodologies or other topics related to information theory, such as local entropy, time variation/evolution of entropy, and entropy cycles, are especially encouraged.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Entropy is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
