Special Issue Information
Dear Colleagues,
The rapid development of wireless communication systems has created a significant problem, namely radio resource scarcity. The introduction of dynamic spectrum management (DSM) aims to increase the efficiency of spectrum resource utilisation using cognitive radio (CR) technology. CR technology can sense the radio environment, analyse the state of the spectrum, create situational awareness, make decisions, perform specific actions and finally adapt to it (e.g., artificial intelligence-based methods). Spectrum sensing is one of the main methods of ‘observation’ applied in CR technology. Joint communication and sensing (JCAS), based on the idea of CR, is one of the crucial trends in developing emerging communication systems. CR technology can be used in mobile ad hoc networks (MANETs), flying ad hoc networks (FANETs) and special-purpose applications. Moreover, software-defined radio (SDR) platforms are commonly used to implement CR solutions.
This Special Issue will bring CR trends, methods, applications and challenges together. Topics of interest include, but are not limited to, the following:
- DSM in CR, spectrum sharing and JCAS;
- Spectrum sensing, radio environment maps, situation awareness, cooperative networks, interference mitigation and data fusion;
- AI for CR, such as machine learning, deep learning, and predictive models;
- Special-purpose applications of CR technology, MANETs, FANETs, unmanned aerial vehicles (UAVs), and 5G and beyond mobile network common aspects;
- SDRs, hardware platforms and antennas for CR.

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. Applied Sciences is an international peer-reviewed open access semimonthly 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.
