Advanced Telecommunication Systems
FEKT-MPA-KS2Acad. year: 2020/2021
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.
Learning outcomes of the course unit
The student is able to: (1) characterize transmission environments and their effects on telecommunication signals, (2) create a channel model, (3) explain and apply methods of elimination of unwanted phenomena in the channel, (4) explain the ways of generating, transmitting and receiving telecommunication signals, (5) estimate the parameters of transmitted signals and use them for advanced methods of signal processing.
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.
