Course description and aims

The main aim of this lecture is to make students understand fundamentals of physical layers of electronic communication systems. Especially, students are expected to learn principles of some modulation and demodulation schemes and to understand how these schemes are applied to real communication systems.

Student learning outcomes

At the end of this course, students will be able to:
1) regard channels as abstract mathematical models,
2) explain how modulation schemes transform baseband signals into bandpass signals,
3) explain how demodulation schemes derive baseband signals from bandpass signals.

Keywords

baseband signal, bandpass signal, amplitude modulation, frequency modulation, phase modulation, coherent detection, non-coherent detection, sampling theorem, digital modulation

Competencies that will be developed

✔ Specialist skills Intercultural skills Communication skills Critical thinking skills Practical and/or problem-solving skills

Class flow

Students are provided with exercise problems about items explained in each class.
