Course detail

Communication Systems

FEKT-BKSYAcad. year: 2017/2018

Students first become familiar with architecture of common analog and digital communication systems (block scheme, basic functions). Then, the building blocks operation and methods of signal processing (source coding, encryption, channel coding modulation, synchronization, etc.) are described. At the end the students obtain an overview of recent communication system types and their particular representatives.
