Special Issue Information
Integrated sensing and communication (ISAC) is one of the key features of the coming sixth-generation cellular system (6G). The ultimate goal of ISAC is to facilitate wireless sensing and communications via uniform infrastructure and signals. Despite the existing related literature, there are still issues open for discussion. For example, how should one evaluate the performance of various ISAC techniques uniformly? What kind of waveforms or frame structures are more efficient in ISAC application scenarios? What is the performance tradeoff between sensing and communication? How would sensing and communication assist one another? In addition to these theoretical investigations, it would also be interesting to further demonstrate the magic of ISAC via prototypes. In this respect, it is already known that communication signals could be exploited in hand gesture and motion recognition, trajectory tracking, etc. Another interesting aspect to study is the possibility of the fast development of a low-attitude economy being one of the most important ISAC application scenarios. It would therefore be interesting to show ISAC implementations for a low-attitude economy in this Special Issue. Hence, the topics that will be covered in this issue include, but are not limited to, the following:
- Fundamental limits and performance analysis of ISAC;
- Advanced waveform, channel coding, and modulation designs for ISAC;
- ISAC-related emerging physical-layer technologies;
- Novel multiple-access designs for ISAC;
- Machine learning for ISAC;
- Channel modeling for ISAC;
- Resource allocation for ISAC;
- Demonstration of ISAC in motion recognition, trajectory tracking, environment sensing, etc.;
- ISAC theory and implementation for a low-attitude economy.

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. Sensors 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 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.
