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.

Not applicable.

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

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).

Lectures:
1. Telecommunication system common architecture, basic building blocks.
2. Formatting and source coding. Compression of voice, video (JPEG, MPEG) and digital data (LZW, Huffman coding).
3. Channel coding. Block and convolutional codes, concatenated codes, Turbo and LDPC codes.
4. Baseband modulation (PAM, PWM, PPM). Line codes. Spectrum and bit error probability calculation.
5. Detection of communication signals in noise. AWGN channel. Binary signal reception, hypothesis testing. Matched filter.
6. Inter-symbol interference. Impulse shaping. Signal equalization (zero forcing, MMSE).
7. Band-pass modulation (AM, FM, MPSK, MSK, GMSK, MQAM). Constellation diagrams, bit error probability.
8. Multiple access systems (deterministic and stochastic). Multiplexing techniques.
9. Communication channel (metallic line, optical fiber, free space). Noise and fading channel. Diversity reception.
10. Spread spectrum techniques, FH/DS-SS.
11. Carrier frequency and phase synchronization. Symbol, frame and network synchronization.
12. Selected telecommunication systems and technology. ISDN, ADSL.
13. Selected telecommunication systems and technology. Satellite communication, optical fiber and wireless links.

Laboratory exercises:
