Seminar "DVB-T coding emulator/simulator (in Matlab)"
A hands-on experience in digital video broadcast (DVB) issues. In this seminar students develop a software package for encoding and decoding digital video for broadcasting. Starting with an MPEG transport stream, the digital data pass through several coding steps until they are eventually modulated onto radio frequency carriers and become analogue signal. The decoding is a roll-back of the same process.
The purpose of the seminar is to create a software testbed for DVB, enabling experimenting with the technology on a desktop computer. Based on DVB technical specifications, each student develops, tests and reports on one module in the pipeline (actually two: the encoder and the decoder). The implementation is done in Matlab and test data will be provided.
Prerequisites: Bachelor or Vordiplom, Matlab experience. Hearing or having heard Telecommunications 1 is strongly 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.
