Selected Topics in Communications Engineering

This seminar is jointly organized by the Institut für Nachrichtentechnik and the Institute of Communication Systems.

Tutors:Matthias Schrammen, Sebastian Nagel, Christian Rohling, and Maria Meyer

Type: Seminar with 3 or 4 SWS

In this seminar, advanced topics of communications technology and information transmission will be discussed. The focus will be on recent developments as well as aspects of system realization.

Participating students work out different topics and present these in talks of about 25 minutes. Apart from the scientific and technical topics, the seminar also emphasizes on presentation skills. These are addressed in a Presentation Workshop which is held early in the semester. This workshop also provides an introduction into the technical topics of the seminar.

Fundamental knowledge of communications engineering, e.g. from the lectures "Kommunikationstechnik", "Information Theory and Source Coding", "Informationsübertragung" or "Signals, Systems and Communication". The number of participants is limited to 16.

Materials: Starting material for the literature research will be provided.

Language: German / English


Introduction and topic assignment will take place on Wednesday, April 14th 2021 at 1:30pm online. A formal registration in the RWTHonline system is required.
