Summer Semester 2014

 

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.

Seminar: "Digital Data Communications - Multi-View Video Streaming"

HIS-LSF course information

Multi-view video systems allow a user to perceive depth in the viewed scene and to display the scene from multiple viewpoints. Stereoscopic 3D video is a special case of multi-view video, where the scene depth is rendered with the help of a specialized display device – head-mounted glasses or an autostereoscopic display. With multi-view video, a scene is synchronously recorded from multiple viewpoints using a multi-camera system, such that it can be displayed from different viewpoints or directions (angles). When multiple synchronized cameras are used to record a scene, viewpoint changes can be directly supported by switching to the desired camera stream. However, to support continuous viewing from an arbitrary viewpoint, the number of physical cameras may grow impractically large. For this reason, efficient multi-view video systems render virtual views at locations between the original viewpoints. 

Multi-view video streaming systems require new approaches for video capturing, transmission and display. In this seminar, we explore the research space for multi-view video streaming, first by an analysis of fundamental system components (coding, rendering, display) and then by focusing on streaming and delivery aspects.

Advanced lecture: Telecommunications II / "Audio/Visual Communications & Networks" (TC-II) (Nachrichtentechnik II / Digitale Kommunikationsnetze)

HIS-LSF course information

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.
