Learning outcomes
|
The aim of the course is to deepen students' knowledge in the field of communication signals and provide the necessary theoretical basis for understanding and further study of communication systems and subjects dealing with signal processing in communication systems. Emphasis is placed on the spectral and energy properties of individual modulations.
The student will gain an overview of the used methods of modulation and demodulation and a theoretical basis in the field of theory of detection in communications for further study of signal transmission and processing in communications.
