Special Issue Information
Dear Colleagues,
Our lives are tightly linked to the oceans on our planet. The resources available in oceans that cover 71% of the Earth have not been fully investigated yet, and natural disasters such as tsunamis attack many peoples. In order to utilize these resources and monitor the ocean environments, research has focused on various state-of-the-art technologies. Digital underwater communication is one of the important core technologies for these issues. When underwater IoT devices are connected to the fusion center, or control messages are conveyed to UUVs, digital underwater communication plays an important role. Unfortunately, even though digital communication in RF (radio frequency) has been developed, underwater environment obstacles, e.g., long propagation times, long multipath channel delay profiles, limited and narrow bandwidths, irregular Doppler shifts, etc., make it difficult to apply modern RF communication technologies to underwater communications. However, reliable and high data rate underwater communication requirements give rise to the development of various sophisticated underwater communication techniques, such as modulation/demodulation, channel estimation, multiple access, etc.

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. Electronics 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.

Benefits of Publishing in a Special Issue
- Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
- Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
- Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
- External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
- e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.
