This course is designed for students who are interested in the fundamental principles of wireless communications and their practical applications. The main learning outcome is that students will gain a deep understanding of key concepts in digital and wireless communications, including transmission in band-limited channels, multi-carrier modulation, and multi-user communication systems. These concepts are crucial for modern technologies such as 5G networks, IoT, and advanced wireless systems. Another important learning outcome is that students will develop analytical skills to evaluate wireless channel models, optimize signal transmission, and design efficient communication systems. A further learning outcome is that students will reinforce their understanding by applying these concepts through hands-on simulations and MATLAB-based projects.
