Summary

Communication devices/systems are all around us. Not understanding their working principles could lead to losses, such as in this video https://youtu.be/xHCUpLBGIKQ. By participating in this lab course on communication systems, you will gain practical knowledge of communication technologies. You will also use this knowledge to exploit vulnerabilities (hack) garage door openers and solve the mystery in this video https://youtu.be/TcnCm2X_4G8.

Detailed Description

This communication systems lab will give students practical knowledge of communication technologies. Specifically this lab will focus on:

Signal analysis, including signal sampling, reconstruction and filtering
Signal modulation and demodulation, and
Software Defined Radio (SDR)

On completing this lab course, students will be able to:

Practically demonstrate their understanding of the fundamental theories governing digital and analog communication systems
Implement signal sampling and reconstruction
Understand filters and apply them to signals
Practically implement signal modulation techniques such as, Amplitude Modulation (AM)*, Frequency Modulation (FM), On-Off Keying (OOK), and Amplitude-shift keying (ASK)
Understand Software Defined Radio (up to an intermediate level), and
Use concepts learned in this course to exploit vulnerabilities in keyless entry systems such as garage door opener or car key fobs.

Teaching methodology

Course participants will work in groups of 2 to complete 4 units of this course. With the exception of Unit 4, all unit requires between 3 to 4 hours to complete. Therefore classes will be held at most 6 times for the entire semester.

If you have any questions regarding the course schedule (meeting days and times) please write me at rockson.agyeman@aau.at
