Course detail
Fundamentals of Telecommunication Systems
FEKT-GFTSAcad. year: 2019/2020
The course deals with analog and digital telecommunications system architectures, with description of the building blocks function and with the methods of signal processing used. The course introduces the basic techniques of signal processing from analog to digital conversion through the source and channel coding, encryption, modulation, to multiple access techniques or synchronization. The basic types of transmission media are presented and their influence on transmitted signals and methods of negative effects suppression are discussed. Selected signal processing techniques are demonstrated in laboratory measurements. Students will use the gained knowledge in related courses oriented to specific wired and wireless communication systems.
