Course description

The communication channel model. Spectral signal analysis. Measurement by spectrum analyser. Random processes, power spectral density, noise sources in communication systems, noise models. Principle of amplitude, frequency and phase modulation, analysis of the analogue systems (AM, FM, PM) and digital systems (ASK, FSK, PSK, QAM) with respect to spectral efficiency as well as resistance to noise. OFDM. Signal to noise ratio (S/N) and BER. Transmission media. Transmission lines. ADSL. Generation of electromagnetic waves, wave equation. Hertz dipole. Antenna parameters. Dipole and unipole antennas. Antennas for different frequencies. Radio links. Mobile communication systems. Optical communication systems: semiconductor laser diodes, optical amplifiers, optoelectronic modulators and photodetectors, multimode and single-mode optical fibres. Integration of communication systems.

Knowledge and skills acquired

Students will be able: to calculate power spectral density of the random signal sequence; to define channel bandwidth needed for signal transmission; to analyse the modulation system with respect to the spectral efficiency as well as the resistance to noise; to choose components of the communication system and to calculate the basic parameters of a radio link and an optical communication system.

Overview of course assesment

Learning outcomes
Upon successful completion of the course, students will be able to:

1. Objasniti razliku spektra periodičnih i neperiodičnih (slučajnih) signala. Izračunati spektralnu gustoću sekvence slučajnog impulsnog niza i odrediti širinu kanala za njihov prijenos.

2. Odabrati odgovarajue parametre i izmjeriti spektar moduliranog signala spektralnim analizatorom.

3. Opisati značajke modulacijskih postupaka: AM, FM, PSK, QAM i FSK. Usporediti modulacijske postupke s aspekta otpornosti na šum i zauzeća spektra. Izračunati vjerojatnost pogreške za dani modulacijski postupak i parametre sustava.

4. Izračunati parametre koaksijalnog kabela i dvožičnog voda. Usporediti i odabrati koaksijalni kabel prema prijenosnim karakteristikama.

5. Objasniti princip generiranja elektromagnetskog vala i valne jednadžbe.

6. Objasniti parametre antena i izabrati odgovarajuću antenu za odabrani radiokomunikacijski sustav.

7. Izračunati parametre usmjerene radiokomunikacijske veze.
