Learning outcomes
|
The aim of the subject is to provide students with basics of radiocommunication technology to support their further study of signal transport and processing in communication and process control. The subject links to communication technology subjects of the bachalar study program.
Student will get an insight in radiocommunication system problems and practical experience in application of modulation methods, demodulation and detection of communication signals.
