Year:   2018/2019    2019/2020    

Tallinn University of Technology

• 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

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

Basic elements of a communications system. Mathematic theory of information transmission. Baseband signals. Passband signals and systems. Limited-bandwidth channel. Signaling over additive Gaussian noise channel. Optimum receiver. Probability of error for different digital modulation techniques. Soft- and hard-decision decoding. Carrier recovery and symbol synchronization. Intersymbol interference. Coherence time and bandwidth of a radio channel. Digital signaling over fading channels.
