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).

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.
• We will introduce an online tool PINGO to make the lectures sessions more interactive for the students. Everybody with a device that connects to the Internet has the possibility to anonymously take part. No sign-up required.
• 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 2018: 25th and 26th
• Re-Main Exam - September 2018: 25th and 26th

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 volunteer to demonstrate your understanding on the task sheet questions and get an additional 1 point on every task you have contributed individually. Multiple students can't claim points for the same task.

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. These points can be earned individually by everyone.
  • Each task sheet contains minimum 3 tasks, which adds up to 18 points total for all tasks in each block. These points can be earned only if you individually volunteer to demonstrate your understanding on the task during the tutorial.
  • 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.
