Winter Semester 2004/05


Seminar “Wireless Audio/Video Transmission”

This seminar introduces the various systems that have been introduced for wireless transmission of high rate audiovisual signals (e.g. digital TV signals). The major standard suite comprises 802.11, 802.15 and 802.16 but the seminar will also introduce the European HiperLAN/2 system.

Purpose: Besides the training in literature / web study and the generation of a report and an oral presentation on a specific subject the seminar as a whole will introduce to you the various derivatives of wireless networks (MAN/BWA, LAN, PAN) as well as the standardisation environment in which they have been developed.
Besides the technical introduction to the systems / system extensions the seminar will also offer topics on the standardisation environment (membership, procedures, IPR framework) under which they have been developed to generate a feeling about what is necessary to develop a system that is widely adopted by industry.

Required Education: Seminar credit points account for your main study period. Therefore Bachelor / Vordiplom is recommended.


Telecommunications I / Digital Transmission and Signal Processing
(Nachrichtentechnik I / Digitale Übertragungstechnik & Signalverarbeitung)

Remark: The course can be given in English in case this will be recommended by the participants in the first lesson.

Digital Signal Transmission and Signal Processing refreshes the foundation that you have layed in “Signals and Systems / Signale und Systeme”. We will, however, include the respective basics so that the various facettes of your introductory study period (Bachelor in Computer Science, Vordiplom Computer und Kommunikationstechnik, Elektrotechnik oder Mechatronik) and the potential main study period (Master in Computer Science, Diplom Ingenieur Computer und Kommunikationstechnik oder Mechatronik) will be payed respect to.

As the basic principle the course will give an introduction into the various building blocks that modern telecommunication systems do incorporate. Sources, sinks, source and channel coding, modulation and multiplexing are the major keywords but we will also deal with dedicated pieces like A/D- and D/A-converters and quantizers in a little bit more depth.
The course will refresh the basic transformations (Fourier, Laplace) that give access to system analysis in the frequency domain, it will introduce derived transoformations (z, Hilbert) for the anylysis of discrete systems and modulation schemes and it will briefly introduce algebra on finite fields to systematicly deal with error correction schemes that play an important role in modern communication systems.

Required Education: “Digital Transmission and Signal Processing” is a course during the main study period and by such requires a solid foundation of mathematics (differential and integral calculus) and probability theory. The course will, however, refresh those areas indispensibly necessary for telecommunications and potential intensification courses and by this open this potential field of intensification to everyone of you.
