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.

Learning outcomes of the course unit

The graduate is able to: (1) describe the common telecommunication system architecture, (2) explain the basic building blocks operation, (3) characterize the transmission media and influences of the transmission environment, (4) explain the methods of signal processing in the sub-parts of the system, (5) discuss the signal processing techniques in specific systems.


Knowledge of bachelor mathematics (integral calculus, solution of equations, fundamentals of probability analysis and statistics) and fundamentals of signal processing (convolution, correlation, filtering, spectrum analysis) are requested.

Planned learning activities and teaching methods

Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations.

Assesment methods and criteria linked to learning outcomes

Students can obtain maximally 30 points for their activities during semester and 70 points for the final exam. The honored activities are as follows: one midterm test oriented to the application of selected signal processing techniques (10 points) and laboratory measurements (20 points). The written final exam is based on the theory as well as calculations (70 points).
