The advanced course "Telecommunications" is intended to give a broad overview of the current research in this field. The course will complement the basic lecture "Telecommunications" that runs in parallel: specific topics are discussed in more detail, beginning with signal processing applications to allow the basic lecture to be ahead with the fundamentals. The advanced course comprises 4 hours per week.
The lectures will cover a wide field that starts from the properties of multimedia signals (speech in particular), discusses processing, coding, and transmission of these signals (including error correction coding and the particulars of wireless multiuser systems) and reaches to image and video coding. Ald basic to understand JPEG coding for images and H264 for video will be presented. The goal is to provide an overview of the large variety of applications that are based on the theory. Another aim is to discuss the formal methods used in research in this field. The lectures cover 4 hours per week, and they are organised in modules of different size that are taught in equal shares by Prof. Goertz and Prof. Rupp.
1. Image and Video Coding (Rupp): Starting with some basic knowledge about the human visual system, we will treat source coding of images and video sequences. Within this we will discuss entropy, quantisation, orthogonal transformations, wavelets and much more. Basics of JPEG as well as modern JPEG2000 image coding are being presented as well as H264 videocoding basics. Moreover a tutorial on 3D techniques and the newest emerging standard HECV is provided.
The lecture on "Image and Video Coding" is (irregularly) on Fridays starting 2 pm-5 pm in lecture hall EI6. First lecture is on March 8, 2013 starting 2:30 pm!
2. Speech Signal Processing and Source Coding (Goertz): Speech as a digital signal, signal properties, speech generation. Representation of discrete-time signals by a limited number of levels so that signal transmission with a limited number of bits becomes possible. In the lectures basic concepts as well as popular practical quantisers are discussed, including uniform quantisation, non-linear predistortion (log PCM), optimal quantisation but also vector quantisation)
3. Digital Communications (Goertz): discrete-time channel modelling of communication systems, simple channel models, how to measure and quantify "information", channel capacity, channel coding: basic concepts, soft- and hard-decision decoding, families of channel codes
4. Multiuser systems (Goertz): widened problem setting compared to classical point-to-point links, multiuser diversity gain, differences between "wireless" and "wired", throughput, fairness, quality of service.
The lectures with the topics 2,3,4, take place on Tuesday in room EI1, with the first lecture on topic 2 (Speech Signal Processing and Source Coding) on 5 March 2013 at 2 pm. Three lectures will be held on each of 9 afternoons from 2pm. The dates are: 5.3., 12.3. 19.3., 9.4., 16.4., 23.4., 30.4., 7.5., 14.5.
There will be printed handouts of the lecture slides.
