Advanced Telecommunication Systems
FEKT-MPA-KS2Acad. year: 2022/2023
The course follows the MPA-KS1 and extends the knowledge especially in the field of environmental impacts on transmission of telecommunication signals. It deals with methods of measurement, modeling and characterization of radio and optical channels, examines the effects of these channels on transmitted signals and describes methods of suppression of negative influences of these channels in selected systems (OFDM, CDMA). The course is also aimed at architecture and performance of selected telecommunication transmitters and receivers, methods of estimating parameters of transmitted signals, advanced methods of synchronization and perspectives of digital telecommunication systems.
