Advanced Studies in Optical Fiber and Wireless Communications

Dear Colleagues,

Thanks to the (r)evolution in optical communication systems (fiber and wireless), many signal processing techniques are being developed for new, energy-efficient, high-capacity, fully transparent, all-optical, and hybrid optical–wireless networks for novel telecom and datacom applications.

Optical fiber communications have played an important role in fast data transmission over long distances, moving from core, aggregation, and metro networks to access networks. Optical wireless communications include technologies covering three optical bands that can be classified based on their typical transmission range as ultra-short-, short-, medium-, and long-range links. Improvements in these technologies are expected to impact the delivery rates of fiber-like data in dense urban areas and customer premises networks, taking advantage of unique and inherent optical carrier characteristics, which are not available in radio-frequency wireless technologies.

The signal processing techniques developed in the field of Optical Communications are not only aimed at networks but also at systems. Application areas include but are not limited to the following: possibilities for increasing data throughput; effective utilization of available bandwidth and wavelength resources; protocols and algorithms for supporting adaptability, low latency, and high link reliability; advanced techniques of computing power, spectral and energy efficiency, power and link budget optimization, network synchronization, multi-carrier modulations, multiple access, and relay-assisted transmissions; advances to meet the system capacity and security requirements of future IoT applications, etc.

For this Special Issue, we invite submissions exploring novel advances, applications, and new trends in signal processing techniques, in both optical and electrical domains, for optical fiber and/or wireless communications. Survey papers and reviews are also welcomed.

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.
