Postdoc in Channel Coding for Optical Communications

jobbeskrivelse:

DTU Fotonik works with all areas of photonic engineering, including a strong focus on optical communications and coding. The postdoc project will be positioned within the Coding and Visual Communication Group, which is part of the Communication Technology Section at DTU Fotonik. The project is part of the INCOM project funded by Innovation Fund Denmark (IFD).

We are seeking a candidate to work on advanced high-throughput channel coding for optical communication. The focus will be on fast forward error-correction (FEC).

Error-correction codes (ECC) are vital in optical communication systems to achieve highly efficient and highly reliable communication. This research position is focussed on high-speed FEC and the interaction with the modulation scheme in optical communication, striving for Tbit/s communication.

Responsibilities and tasks

For high coding performance, soft-decision (SD) FEC will be applied. One scheme to study is based on concatenated coding with an inner SD FEC. For high-speed and high-reliability, a fast hard-decision (HD) FEC, is a good choice for the outer code. Concatenated coding combining an SD Hamming code as inner code and a staircase code as outer code will be considered as reference. The goal is to design even better coding schemes. For SD coding, codes as LDPC, LDGM, and Polar Codes can also be considered, as well as simple SD decoding of the outer code.

The channel coding can encompass both FEC and coding for probabilistic constellation shaping, e.g. in coded modulation communication schemes using higher order modulation. The performance shall be evaluated by analysis and simulations and compared with information theoretic bounds.

Striving for Tbit/s throughput, fast algorithms are a vital part of the research. This includes analysis of the influence on the performance and important implementation aspects as energy efficiency.

The postdoc project will be part of the INCOM project centred at DTU Fotonik, and it will be in close collaboration with other coding activities within the INCOM project and at DTU Fotonik, as well as external partners. Experimental demonstrations of selected devised coding schemes in optical transmission are an integral goal in this joint work.

• You are striving for excellence within the research topic
• You are driven by pushing boundaries
• You are motivated by both individual and team accomplishments

Apart from the research outlined above, the postdoc position may involve a limited amount of teaching mainly in the form of supervising student projects.

Qualifications

Candidates should have a PhD degree or equivalent, within the area of coding for communication, preferably for optical communication. A strong background in coding for communication is required. Experience with coding for optical communication, coded modulation, rate-adaptive probabilistic constellation shaping and high order modulation schemes will be a plus.
