Integrated Sensing and Communications: Latest Advances and Prospects

Dear Colleagues,

Signal processing procedures played an important role in the early development of combined sensing and communication systems, due to the need to use a limited spectrum more efficiently and reduce hardware expenditures. At first, dual-function radar communication systems prevailed over the field of joint sensing and communication. However, this area has since evolved into a more complex archetype called integrated sensing and communication (ISAC), which takes into account various types of sensing and communication interactions and considers other sensors besides radar. Wireless sensing was for a long time a separate technology developed as a complement to mobile communication systems. General sensing should be integrated into 6G mobile communication systems to open up new services for 6G.

The capabilities of ISAC will enable many services that mobile communication system operators offer. These include localization and tracking, high-accuracy positioning, imaging for biomedical and security applications, natural disaster monitoring, activity and gesture recognition, defect and material detection, and numerous other services. Designing future ISAC systems requires many challenges to be overcome, such as selecting transmitter signals, processing received signals, estimating channels, and tracking and allocating resources. In recent years, several signal processing techniques have been introduced to address these challenges, resulting in a growing interest in advanced signal processing methods for designing ISAC and implementing it in future wireless networks. Despite drawing significant attention from both academia and industry, many open problems still require investigation. This Special Issue aims to provide a collection of technical papers from academia and industry, focusing on major trends related to ISAC. Contributions may be focused on topics including but not limited to the following:

• Communication technologies assisted by sensors;
• Advanced networking technologies assisted by sensors;
• Experimental demonstrations and prototypes of ISAC for sensors;
• Performance evaluation for ISAC with sensors;
• Security and privacy issues of ISAC;
• Application of advanced ISAC technologies;
• Progress in the standardization of ISAC;
• Integrated sensing, communication, and computing for ISAC;
• Centralized or distributed machine learning for ISAC.

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.
