Special Issue Information
Dear Colleagues,
Optical transmission systems form the backbone of global telecommunication infrastructure and serve as a key component of our information based society. Since their first deployment in the early 1970s, many technological innovations, such as erbium-doped fibre amplifiers (EDFAs), wavelength division multiplexing (WDM), forward error correction, Raman amplification and so on, have enabled an exponential growth of the data traffic. Currently, the so-called fifth generation of fibre-optic systems has been benefited by the advances in high-speed digital signal processing (DSP) and the global adoption of coherent detection, which enabled the transmission of multi-level and multi-carrier modulated signals at bitrates that exceed 400 Gbit/s. Key to this success has been the mitigation of linear impairments, such as, chromatic dispersion and polarization mode dispersion by appropriate DSP algorithms, leaving fibre nonlinearity and amplified spontaneous emission as the next most important barrier. Even with multi-mode/multi-core fibre systems, which have been recently proposed as alternatives to increase spectral efficiency, the nonlinearity impact cannot be avoided. As a result, the development of advanced digital methods that can enable compensation of the nonlinear transmission impairment will be crucial for the capacity expansion of next generation fibre communication systems.
This Special Issue aims to explore recent advances and future trends of digital signal processing for non-linearity mitigation in high capacity fibre transmission systems. Topics of interest include, but are not limited to the following areas:
- Advanced Digital Back Propagation methods
- Volterra based nonlinear equalization
- Machine learning based nonlinear DSP methods
- MIMO non-linear equalizers for few mode/core transmission systems
- DSP for multi-carrier transmission systems (OFDM/Nyquist)
- Channel coding in the presence of non-Gaussian noise
- Mixed signal processing
- Autonomous transponder cooperation/transponder orchestration

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.
