Qualification outcome
Areas of Competence: Knowledge and Understanding; Use, application and generation of knowledge; Communication and cooperation; Scientific self-understanding / professionalism.
After successful completion of this module, the students will be able to develop intelligent methods which can be used to automatically adapt the data rate of digital data transmission systems with respect to the available frequencies.
The students will be capable to describe concepts of Software Defined Radio (SDR) and Cognitive Radio (CR), and will be able to use them in digital transmission. Furthermore the students will acquire a deep knowledge about different SDR architectures and will be capable to compare and evaluate their realization. Based on the Red Pitaya board, they will have the opportunity to visualize the functionality of different components and will obtain experience about the requirement of transmitter and receiver design.

In lab experiments, the students will emulate different data transmission methods. They will use the Red Pitaya board as a platform and integrate their transmitter and receiver C/C++ programs in order to perform adaptive data transmission. They will exploit different modulation schemes as well as different receiver concepts. The students will be able to test and measure the performance of their developed systems with respect to different transmission scenarios.
Due to group-wise problem solving with typically just two students per group, problems can be solved efficiently. Soft skills like communication skills will be trained. The students will learn to split complex problems into sub-tasks and to join the corresponding sub-results.
