Goal of subject
• to introduce the mathematical theory of telecommunications, and basic types of communications channels • to teach how to estimate the capacity of a channel • to introduce demodulation and symbol detection techniques • to introduce the sources of intersymbol interference and methods to reduce its effects in bandlimited channels • to introduce time-frequency characteristics of radio channel and their effect on channel capacity

Learning outcomes of the subject
After having successfully passed the course a student: • is able to calculate the logarithmic measure of information and data rate of a data source • is able to estimate the channel capacity in presence of noise and distortions • knows basic types of demodulators and symbol detectors and is capable of calculating symbol error probability • is able to choose proper waveforms and implement diversity techniques for a communications channel under design to reduce the effects of intersymbol interference
