By participating in the module events, the student gains knowledge of current scientific developments in the field of digital communication technology.
The student is then able to independently work on a task from a current subject area of communications technology in a scientific manner and to prepare a written thesis. In addition, the student can present the knowledge he has developed in front of an expert audience.
Various current topics from the areas of digital communication technology (e.g. source, channel and network coding, optical transmission technology, information theory) are selected for the seminar, which the students work on independently.
Each student summarizes the results of his or her work in writing and gives a scientific lecture, which is followed by a scientific discussion.
The following modules should be successfully completed before participation:
- Lectures on digital communications
- Depending on the topic, relevant specialist lectures, if applicable
Teaching and learning methods
Each student is assigned a research assistant as a supervisor, who instructs them in researching and reading scientific specialist literature and guides them in writing the seminar paper. An introductory event conveys the basics of scientific lectures or presentations.
Each participant works on an individual technical task. This takes place in particular in independent individual work by the student.
Module examination with the following components:
- Written thesis of the results (30%)
- 20-minute scientific lecture on the topic and subsequent 10-minute discussion (50%)
- Participation in the discussion (20%)
With with the increasing number of devices connected to the internet and the growing number of M2M type communications, massive random access has become a crucial topic in the design of communication systems. The student's task is to understand the concepts of massive random access. The Two main resources are  and .

The student's task is to understand a recently introduced coding scheme, namely polarization-adjusted convolutional (PAC) codes . In addition to encoding and decoding schemes presented in the papers below [2,3], the students asked to study the error exponent for concatenated code ensembles , which is closely related to the good performance of not only concatenated polar codes but also PAC codes.
[quantum] Recent results from QIP 2021 (Quantum Information Processing conference)
The QIP conference is one of the most important conference in Quantum Theory. The student will have the freedom of choosing one article from the latest conference and will then have to understand and report on the article.

Forward Error Correction (FEC) for High-Throughput Optical Communication
Forward Error Correction (FEC) for high-throughput optical communication has gained growing interest in the research community. The always-growing data rate (soon expected to reach 1 Tb/s) makes it necessary to look for low-complexity and low-power consumption solutions. Soft-decision (SD) decoding can guarantee top performances but it is not feasible in this setting due to its high complexity. Hard-decision (HD) decoding, especially of product codes and product-like codes, is regarded as an appealing solution due to its good performance-complexity trade-off. During the recent years, many researcher have tried to fill the performance gap between HD and SD decoding performances while keeping the complexity low.
Staircase codes are a class of product-like codes introduced in  with their HD decoding algorithm. They offer a good performance-complexity trade off, and they are adopted in recent optical standardizations (e.g. 400ZR standard). To enhance further their performances, they can be used as outer code of a concatenation scheme - with an inner SD decoded code.
The task of the student is to learn about performance-complexity trade-off in FEC for optical communications, to understand the structure and HD decoding of staircase codes and their application in the concatenated structure.
