Digital Communications

Announcements

In Summer Semester 2020, this course is offered online in "flipped classroom" style using the teaching platform Moodle, i.e., the course will consist of selfstudy with question times.

Information will be available from this course website but mainly it will be distributed in the Moodle courses. Please visit this website frequently for updates and register in Moodle (see below) if you want or have to take these courses.

E-Learning Platform Moodle

The e-learning platform Moodle (lecturelab) will be used for further lecture & lab announcements and the distribution of the tutorial sheets. The registration for both courses is not open yet.

Description

Organization

The course "Digital Communications" consists of the following parts (7 Credits in total):

  • Lecture (4 h/week) and Exercises / Tutorials (2 h/week), Tuesday, 08:30–12:00 h and Thursday, 14:00–15:30 h
  • An accompanying Lab (6 projects, 5 Credits) is offered and strongly recommended (details see below).

Overview

An introduction into the basics and mathematical fundamentals of digital communications is given. The lecture covers the following topics:

  • Introduction
  • Equivalent Complex Baseband
  • Pulse-Amplitude Modulation (PAM)
  • Variants of PAM Transmission Schemes
  • Signal-Space Representation
  • Digital Frequency and Phase Modulation
  • Channel Models
  • Equalization of Dispersive Channels
  • Orthogonal Frequency-Division Multiplexing (OFDM)

Prerequisites

Basic knowledge in the fields of

  • of signals and systems
    (Fourier and z transform; sampling theorem; random variables and stochastic processes)
  • fundamentals of (analog and digital) communications
    (linear modulation formats; maximum-likelihood and maximum a-posteriori estimation; bandwidth and power efficiency)

is assumed.

Literature

Subsequently literature for further reading or to acquire the prerequisites for the course is listed. The "Semesterapparat" for this lecture can be found at here.
