Summer Semester 2012
Bachelor- and Master Seminars
In preparation for your bachelor- or master thesis we offer bachelor- and master seminars. These seminars do combine the preparation of a special research topic incl. structured literature research and state-of-the-art analysis with learning the documentation and presentation skills needed in every industrial or academic job.
Bachelor- and master seminars are recommended or even mandatory in various study programs and will be dimensioned and credited appropriately. You will have to participate in regular meetings (biweekly during the semester, monthly during lecture free periods) and present your results to your peers.
Prerequisites: Bachelor- and master seminars are directly related to the prospective bachelor- resp. master thesis and therefore do require that you have all necessary requirements for starting the respective thesis. In addition you must have been donated a thesis topic by the telecommunications lab. Matlab experience, hearing or having heard Telecommunications I (+ Telecommunications II in case of master seminar) is strongly recommended.
Advanced lecture: Telecommunications II / “Audio/Visual Communications & Networks” (TC-II) (Nachrichtentechnik II / Digitale Kommunikationsnetze)
Remark: The course will be given in English in case this will be recommended by the participants in the first lesson.
Audio/Visual Communications & Networks will deepen your knowledge on modern communications systems. It will focus on wireless systems since from a telecommunications perspective the combination of audio/visual data – meaning inherently high data rate and putting high requirements on the realtime capabilities of the underlying network – and wireless transmission – that is unreliable and highly dynamic with respect to the channel characteristics and its capacity – is the most demanding application domain.
The lecture will build on the foundation layed as well in “Signals and Systems / Signale und Systeme” as in “Digital Transmission and Signal Processing / Digitale Übertragungstechnik und Signalverarbeitung” and it will apply the building blocks introduced there onto the various communications systems. The course will aim at being self-contained, however, it will not be able to repeat basic mathematical concepts and tools introduced in Telecommunications I.
As the basic principle the course will study and introduce the building blocks of wireless communication systems. Multiple access schemes like TDMA, FDMA, CDMA and SDMA are introduced, antennas and propagation incl. link budget calculations are dealt with and more advanced channel models like MIMO are investigated. Modulation and error correction technologies presented in Telecommunications I will be expanded by e.g. turbo coding and receiver architectures like RAKE and BLAST will be introduced. A noticable portion of the lecture will present existing and future wireless networks and their extensions for audio/visual data. Examples include 802.11 (with the TGe Quality of Service extensions), 802.16a and the terrestrial DVB system (DVB-T, DVB-H).
Required Education: “Audio/Visual Communications & Networks” 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 build on the mathematical concepts and tools tought in Telecommunications I while trying to enable everyone to follow and to fill gaps by an accelerated study of the accompanying literature. “Signals and Systems” as well as “Digital Transmission and Signal Processing” are strongly recommended but not required.
Remark: Practical course held in german as part of a series of practical courses (not an independent module).
Der Lehrstuhl Nachrichtentechnik beteiligt sich im Sommersemester 2012 im Rahmen der Versuchsreihe “Mechatronisches Praktikum” mit einem Versuch zur Digitalen Übertragung an einer Veranstaltung für Studierende der Mechatronik im 2. Studiensemester.
Der Praktikumsversuch zur digitalen Übertragung behandelt Grundlagen der Signalbeschreibung im Zeit- und Frequenzbereich, einfache analoge Modulationsverfahren sowie die Grundlagen der digitalen Modulation mit einem Ausblick auf OFDM. In dem Versuch werden mittels Spektrumanalysator, Signalgenerator und Oszilloskop analoge und digitale Signale sichtbar gemacht und den Studierenden werden die Eigenschaften verschiedener drahtloser Übertragungsarten an den Beispielen FM-Radio, analoges und digitales Satellitenfernsehen (DVB-S, DVB-S2) sowie anhand des digitalen terrestrischen Rundfunkstandards DVB-T näher gebracht.
Die Mechatronischen Praktika bietet den Studierenden einen komprimierten Einblick in wichtige Lehrgebiete, die sie im weiteren Verlauf ihres Studiums vertieft kennen lernen können.
