Delay-Doppler Domain Communications for Future Wireless Networks 2nd Edition

Dear Colleagues,

Delay-Doppler (DD) domain communications have demonstrated appealing advantages in terms of meeting the stringent requirements for future wireless communications. A typical example is the orthogonal time frequency space (OTFS) modulation that was proposed by Prof. Hadani et al. in 2017. The related design, analysis, and application of DD domain communications have received significant attention from both theoretical and practical viewpoints, where many recent advances have been reported. Those advances are usually built on the application of communication theory, signal processing, and information theory in the DD domain.

The distinct feature of DD domain wireless channels motivates many novel DD domain designs. Achieving further progress on this front calls for the full exploitation of the DD domain channel, innovative adaption of conventional communication approaches, and improved understanding of communication theory, signal processing, and information theory. The main objective of this Special Issue is to exploit the new opportunities of DD domain communication for future wireless networks by collecting new ideas, the latest findings, state-of-the-art results, and comprehensive survey data about DD domain communications. Specifically, this Special Issue will accept unpublished original papers and comprehensive reviews focused on (but not restricted to) the following research areas:

• Fundamental limits for DD domain communications;
• DD domain information theory and waveform designs;
• DD domain orthogonal and non-orthogonal multiple access designs;
• DD domain channel estimation, signal detection, and transceiver designs;
• DD domain MIMO and massive MIMO designs;
• DD domain communications for URLLC;
• Channel coding for DD domain communications;
• Novel applications of DD domain communications (e.g., radar sensing and localization);
• Machine learning/AI-enhanced DD domain communications;
• Security and privacy issues in the DD domain;
• Intelligent reflecting surface (IRS)-assisted DD domain communications;
• DD domain communications in millimeter-wave and terahertz frequency bands;
• Channel measurement and modeling in the DD domain;
• System-level simulation, prototyping, and field tests for the DD domain.

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 250 words) can be sent to the Editorial Office for assessment.

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.
