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)

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.

Subsequently literature for further reading or to acquire the prerequisites for the course is listed.

The password for registering for this course will be distributed at the first lecture.

The lab Digital Communications consists of the following six experiments:

0. Introduction to MATLAB
1. Digital Pulse Amplitude Modulation
2. Implementation of PAM Transmission in MATLAB
3. Variants of PAM Transmission Schemes
4. Noncoherent Reception (NEW!)
5. Signal Space Representation

UPDATE: There will be no Friday group this semester!

There will be 3 main groups: Group "W", "T" and "F" on Wednesday (1pm to 6pm), Thursday (8am to 1pm) and Friday (1pm to 6pm), each with 10 teams of 2 students. These teams will execute the six lab experiments, probably at the following dates:

You will get a printed copy of the lab manual as soon as available.

The lecture starts on Tuesday, April 14, at 8:30 in room H45.1 ("blauer Hörsaal").
Please attend this lecture if you want / have to take part in the lab couse!

The e-learning platform Moodle (lecture / lab) will be used for further lecture & lab announcements and the distribution of the tutorial sheets.
The password for registering for the lecture course will be distributed at the first lecture! For the lab course no password is needed.

The exam inspection of the 1st exam on August 3 will take place on Monday, September 28, 16:00 h, at room 43.2.227 (institute's library).

The second exam is scheduled for October 2, 10:00h in room 43.2.101.

Allowed auxiliaries (see lecture notes or official list of exams in notice board at entrance of  room H45.1):

• pencils, rulers
• non-programmable calculator
• 2 pages (A4; one sheet on both sides), hand-written by the student; no copies, printouts etc. allowed; will be collected after the exam

The exam inspection of the 2nd exam on October 2nd will take place on Tuesday, October 30th, 13:00 h, at room 43.2.227 (Institute library). Please note that the 1st exam on August 15th is not available for inspection on this date.
