Description
Organization
The course "Digital Communications" consists of the following parts (7 Credits in total):
- Lecture (4 h/week), Tuesday, 08:30–12:00 h
- Exercises / Tutorials (2 h/week), Thursday, 14:00–15:30 h
An accompanying Lab (6 projects, 5 Credits) is offered and strongly recommended.
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.
Subsequently literature for further reading or to acquire the prerequisites for the course is listed. The "Semesterapparat" for this lecture can be found at https://ulm.ibs-bw.de/aDISWeb/app?service=direct/0/Home/$DirectLink&sp=S127.0.0.1:23002&sp=SWI00000152&noRedir.

Lab 2016
The lab Digital Communications consists of the following six experiments:
- Introduction to MATLAB
- Digital Pulse Amplitude Modulation
- Implementation of PAM Transmission in MATLAB
- Variants of PAM Transmission Schemes
- Noncoherent Reception
- Signal Space Representation
Scheduling and Organisation
Depending on the number of participants, There will be 2 groups this year, probably on Wednesday (1pm to 6pm) and on Friday (8am to 1pm) (and/or maybe on Tuesday (1pm to 6am)), each with up to 12 teams of 2 students. These teams will execute the six lab experiments, probably at the following dates:
| Project: | Calendar Week: | Dates (W/F): | Supervisor: |
| M | 17 | 27./29. April 2016 | Günther Haas |
| 1 | 19 | 11./13. May 2016 | Günther Haas |
| 2 | 20 | 18./20. May 2016 | Günther Haas |
| 3 | 22 | 01./03. June 2016 | Günther Haas |
| 4 | 23 | 08./10. June 2016 | Günther Haas |
| 5 | 25 | 22./24. June 2016 |
Registration etc.
In the first lecture on Digital Communications you will get further details concerning the organisation of the lab as well as the the registration process.
