Requirements

Exam and personal project works. The course can be taken either for 5 or 7 credits. In the basic version (5 cr), the scope and level of the personal project works are more narrow than in the extended (7 cr) version. NOTICE! *** 7 cr implementation is basically needed, or at least strongly recommended, for those targeting to study transmission techniques and wireless communications in more details. *** The exam and the project works should be done during the same academic year.
Completion parts must belong to the same implementation

Learning outcomes

The student is able to identify the most common signal level phenomena and signal processing methods behind electromagnetic transmission systems as well as their significance to transmission. These include noise, modulation, and filtering, among others. The student is able to apply tools of signal and system analysis, such as Fourier transform and convolution, to study, among others, the effects of distortion, noise, and interference caused by the transmission channel and electronic components. The student is able to explain the characteristics of random signals such as correlation, stationarity, ergodicity, power spectrum, and probability distribution and is able to describe the related mathematical models. The student is able to explain the characteristics of bandpass signals, such as envelope, phase, and spectral content, and is able to describe the related mathematical models. The student is able to explain the function and characteristics of most common analog and digital modulations used in communications. The student is able to justify for practical design decisions from the viewpoint of signal power, bandwidth, and hardware implementation. The student is able to identify the basic resources related to designing communication waveforms and devices such as power and bandwidth and is able to explain the related trade-offs. The student also identifies the basic modules of radio electronics, such as filters and mixers, and is able to explain how they work. The student is able to identify the basic concepts of information theory such as information, entropy, mutual information, and channel capacity, and is able to explain their significance to transmission. After completing the extension part (7 cr) the student is able to explain and analyze properties of communication waveforms and the operation of communication devices using complex-valued signal models, and based on this, design new communication waveforms.
