Communication systems 2
FEKT-BKC-KS2Acad. year: 2019/2020
Following the subject Communication systems 1, students first become familiar with radio interface of communication systems (radio receiver and transmitter conception and architecture, level of their digitization, software defined radio) and with the specific building blocks function (amplifiers, mixers, oscillators, frequency synthesizers, filters, etc.). In the next part, the introduction to the current wireless communication systems will be given (fundamentals of radio and television broadcasting, satellite communications, cellular radiocommunication systems, etc.). Following part will be aimed at voice and data transmission via public switched telephone networks (network digitalization, modems, ISDN and xDSL technologies). Last part of the subject will be focused at the data transmission and network technologies (fundamentals of optical communication, network topologies, wireles networks PAN, LAN a WAN, digital hierarchy SDH/SONET, network components, protocols and services, etc.).
Learning outcomes of the course unit
The graduate is able to:
1. Orientate oneself in current wired, optical and wireless communication systems for the transmission of audio, video and data signals,
2. describe their architecture, eventual network structure and communication protocols used,
3. explain and apply methods of signal processing and techniques of sharing of communications resources,
4. explain their specific circuit solution especially with the focus on radiocommunication systems
Fundamentals of signal processing, electronics, and communication systems at the BPC-KS1 course level are required.
