The lecture "Kommunikationstechnik" is part of the modules

  • Communications Engineering BIK1.X (mandatory),
  • Computer Engineering BTI1.X (mandatory) and
  • Micro and Nano Electronics BME1.X (required elective)

in the 5th semester of the Bachelor program "Elektrotechnik, Informationstechnik und Technische Informatik".


In this one term lecture theory and practice of digital transmission of information is discussed. After an introduction to information theory of sources and transmission channels the main elements of modern digital communication systems are discussed:

  • source coding
  • channel coding
  • modulation
  • multiplex and multiple access methods.

The goal of this lecture is to teach the basics of the individual parts as well as to give the system overview which is necessary for the understanding of complex transmission systems. Here, the information theoretical background, the principle bounds, and the interaction of the individual parts are of particular interest.

The practical application will be discussed with numerous examples, e.g.,

  • speech and channel coding in GSM/UMTS mobile radio network
  • data compression of the facsimile transmission
  • MPEG video coding
  • error correction in CD and DVD systems
  • transmission technology of the GSM/UMTS mobile radio network.

Particular topics can be examined at the laboratories "Communications Engineering" and "Real-Time Audio Processing" in experiments which are coordinated with this lecture. Furthermore this course is harmonized with the special lectures "Advanced Coding and Modulation" and "Digital Speech Processing I and II" of the Master program.
