Learning outcomes
At the end of the course, students will have the skills to analyze and design digital signal processing algorithms for energy-efficient communications systems. In particular, students will be able to: analyze digital systems in time-domain, frequency-domain, Z-domain; design digital filters; design multi-rate digital signal processing systems; design adaptive filters. Finally, the student will know the methodologies for analyzing and designing efficient signal processing blocks taking into account the required energy resources.
Course contents
- Discrete-time signals, spectral representation, convolution, and correlation operators.

Teaching methods
The lectures are supported by some design examples to solve practical problems in digital signal processing by writing Matlab code: audio source localization, audio reverberation, and channel equalization. The code developed in the class is available to the students for further development.
Assessment methods
Pre- and post-tests will be used to assess skills in analyzing and designing digital signal processing algorithms in real-world applications.
All students will show substantial improvement in stated learning outcomes, as indicated by pre- and post-evaluation of real problems.
Teaching tools
Lectures and exercises are carried out with the help of a personal computer and the Matlab platform freely available to students. There are also tutorials on audio and video coding techniques (JPEG, MPEG, and MP3) and processing sensors' data.
