After successful completion of the course, students are able to understand and apply the methods described unter the item "Lehrinhalte". This includes the design of vector quantizers or the implementation of model-based source codecs that are used in mobile phones.

Source coding is a key technology for mobile radio, MP3, JPG, and video transmission. We discuss the theoretical foundations for lossy source coding (rate distortion theory and asymptotic quantisation theory) as well as practical coding schemes and vector quantisation. For practically relevant correlated source signals we extend the theory and we also discuss practical code design that are structurally based on results from information theory. Those schemes include predictive coding, which is used e.g. in speech transmission in mobile radio, as well as subband coding, which is part of MP3-Audio.

The course will be help online. Slides are presented which are available under

Students are supposed to work through the material in advance of the lectures; details of the schedule are given in the lectures slides.

 The slides of the last lecture on CELP speech coding (not relevant for the exam) are available here:
