The registration will open on Friday 13.09. at 10:00 here in CMS. Each individual can register only for one slot and the slots are reserved in a first come first serve basis. De-registration (and slot changes) are possible until 25.09, 10:00. Everyone who has passed both the blocks will be able to register for an exam slot.

Please make sure you are also registered in the LSF (HISPOS) to be allowed for the exam.

If you have any questions regarding the procedure, please contact me (Harini).

Course Details

Introduction

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).

Prerequisites

"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 taught 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.

Course Structure

Basic Rules

  • Please note that small changes and corrections will be applied to the lecture notes throughout the semester. If you find mistakes or have suggestions how to enhance the lecture notes we appreciate your input! 
  • Please don’t hesitate to tell us if you have any comments or suggestions related to lecture notes, task sheets, exercises or even organization things. We will improve it soon so you can benefit from it, not only future students.
  • There will be printed weekly quizzes with 5 questions for 15 minutes every week on Tuesdays from 12:15 - 12:30. These quizzes are graded individually and the points will be published online.

Lectures

  • Place: Campus C6. 3. Room: 9.05
  • Time: Tuesday 12:00 - 14:00  and Wednesday 08:30 - 10:00

Tutorial

  • Place: Campus C6. 3. Room: 9.08
  • Time: Wednesday 12:00 - 14:00

Exam Dates

  • The exams will be held as ORAL exams.
    We will schedule all exam slots in the two days as given below. The exact time of each slot and how you can choose a certain slot will be announced at a later date.

  • Main Exam - July 2019: 23rd and 24th
  • Re-Main Exam - October 2019: 1st and 2nd

Task Sheets

  • Task sheets are issued on Tuesdays after the lecture and are available online.
  • You do not have to submit the solutions, instead work on the tasks until the following tutorial.
  • During the tutorial you can solve the task sheet questions and get 1 point on every task you have contributed individually.

Correction

  • The quizzes and task sheets for this course will be divided into two parts (6 in each block respectively). It is necessary to pass both the blocks individually to be eligible for the exam.
  • Weekly Quizzes and Task Sheets:
    • Each weekly quiz are worth 5 points total, which adds up to 30 points total for all quizzes in each block.
    • Each task sheet contains minimum 3 tasks, which adds up to 18 points total for all tasks in each block.
    • Final points are calculated by adding up over all quizzes and task sheets within a block.
    • You need minimum 20 points in total to pass a block and must pass both block A and B to be eligible for the exam.

MATLAB

  • Since March 2012 the UdS has a MATLAB campus license which can be used by all university students for non-commercial purposes.
  • CIP pool at Saarland university provides access.
  • SSUM Signals and Systems Using Matlab package: a collection of demonstrations and exploratory applications for signal processing. It demonstrates extensively the concept of convolution, Fourier Analysis, FIR and IIR filters, modulation and much more. To use all examples the Matlab "Signal Processing Toolbox" is required (available in the CIP-room and included in Campus License).
