PhD scholarship in Error Correction Coding and shaping for Optical Communication

DTU Fotonik has a strong focus on optical communications and coding as well as working within all areas of photonic engineering. We are hereby announcing a PhD position at DTU Fotonik within the topic of information theory and error correction coding and shaping for optical communication. This project is part of collaboration between DTU Fotonik and the Institute for Communications Engineering (LNT) at the Technical University of Munich (TUM) within the EuroTech Alliance. Starting date is in summer/autumn 2018.

Project description
We are looking for a candidate to work on error correction coding and shaping for optical communication. The subject of this project is efficient coding techniques for high-speed optical communication. The focus will be on forward error-correction (FEC), as well as the combination of FEC with (probabilistic) shaping. The solutions should be efficient both in terms of performance and complexity.

Coding and signal processing techniques for fiber are necessary to achieve the highest data rates. Practical aspects such as implementation complexity and energy consumption play a central role in the choice of algorithms. In the project, advanced coding shall be designed and developed for specific high-speed optical channels and devices. Novel channel coding schemes shall be explored for advanced optical channels such as regenerative channels. The project involves the interaction and combination of error-correcting coding and pre-coding/shaping.

To achieve fast coding and decoding, the project will study product codes based on hard-decision decoders, extended to include erasures or low-resolution soft decision decoding, as well as combined with shaping. Different structures such as staircase codes, block codes, generalized product codes etc. will be studied and compared, including the analysis of error-floors. Algorithms for fast decoding will be devised, analysed and simulated. Selected codes will be combined with probabilistic shaping.

The PhD project will be associated with the research centre of excellence SPOC at DTU Fotonik and will be in close collaboration with activities within the centre on information theory, capacity and advanced coding. The PhD project will involve both theoretical and experimental studies and joint experiments with other SPOC team members, e.g. experimentally testing the novel coding techniques in the optical communication lab at DTU Fotonik. The project will be part of collaboration with Prof. Gerhard Kramer, LNT, TUM.

Candidates should have a master’s degree in engineering or a similar degree with an academic level equivalent to the master’s degree in engineering. Good communication skills in written and spoken English are a must.

Approval and Enrolment
The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes at DTU. For information about our enrolment requirements and the general planning of the PhD study programme, please see the DTU PhD Guide.   

The assessment of the applicants will be made by Professor Søren Forchhammer.
