Learning outcomes:
After successfully completing this course, students will have obtained sound basic knowledge and system expertise in the field of communication technologies. Students will acquire the skills needed to implement software for use in communication systems based on the basic principles of communications engineering.
They will become familiar with the concepts and systems of communications engineering, enabling them to work independently with new future standards. This will become more and more important in the course of their professional lives and aid them in driving innovative developments in the diverse fields of communications technology and embedded systems, for example.
Through hands-on work in the practical part of the course, students will learn to apply the knowledge they have acquired in the lecture to concrete tasks, visualize it with simulation tools and then present their work results. In this way, several core competencies are acquired: visualization and the successful presentation of scientific and technical content, as well as the mastery of simulation tools.
By simulating, preparing and presenting their simulation results together in small groups, students will also learn how to work in groups (team skills).

Teaching methods/Media:
Lecture: Board, projector, flipchart, demonstrations with mobile measuring equipment
Seminar: The seminar is accompanied by a lecture and supplemented by simulations on selected topics of the lecture. Under the guidance of a lecturer, students will independently carry out simulations in small groups using professional simulation tools (e. g. Mathworks MATLAB, Orcad PSPICE, etc.).
The simulation results will be prepared jointly by the student groups and then presented in the seminar for their fellow students.
