New Advances in New-Generation Communication and Symmetry

Dear Colleagues,

The past decade has witnessed tremendous increases in data throughput and the number of connected nodes, and recent studies have also foreboded these increases in next-generation communication systems and future networks. Those tremendous increases will undoubtedly result in increasingly stringent requirements of spectral efficiency and energy efficiency. To meet these two requirements, the “symmetry” could be widely applied in signal processing, transforming, transmit protocols in future communications, such as index modulation, Intelligent Reflecting Surfaces (IRS)-based/reflecting, Space Time Coding and Orthogonal transforming, which have attracted researchers’ attention in recent years. Different from conventional schemes, “symmetry” in communications could lead to one or more dimension(s) that considerably enhance the spectral efficiency under proper system configurations.

Motivated by these observations, this Special Issue aims to capture the state-of-the-art advances in symmetry concepts for future communications and outline the possible future research directions. The topics of interest include but are not limited to the following:

• Symmetry in Communications Theory and Future Networking Architecture;
• Symmetry in Matrix Theory and Its Applications to Future Communications;
• Symmetry in Modulation and Coding Theory for Future Communications;
• Symmetry in Reflecting Model and Intelligent Reflecting Surfaces (IRS) Technology;
• Symmetry in Communication Systems, Transformation and Protocols;
• Symmetry in Secure Communication Systems and Protocols.

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. Symmetry 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 2400 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.
