This course serves as an essential preparation for students aiming at a study or career relevant to wireless communications and/or sensing. This course extends the knowledge of a radio system to its comprehensive function and performances in real-world scenarios.
While radio systems are designed to perform optimally in specific application scenarios and use cases, the system design needs to be optimized to countermeasure the challenges when applied in the uncontrollable environment. The key fundamental aspects of both the designable system and the uncontrollable radio propagation channel will be addressed in this course.
At the end of the course, the student can:
- understand and calculate a wireless link budget incorporating transmitter, over-the-air channel, and receiver aspects;
- explain important aspects concerning wireless propagation channels (propagation path loss, small-scale and large scale fading, statistical/empirical/deterministic models of channels);
- design and implement a radio channel measurement for specific scenarios (examples: body area networks, in-on-off body communications, indoor Wi-Fi communication/sensing , outdoor LTE communications, vehicle-to-everything communications, in-foliage communications/sensing, unmanned aerial vehicle air-to-ground communications);
- conduct radio channel measurement and/or ray tracing/launching simulation, analyze the measured radio channel, process the data, and interpret the observations;
- present the project (motivation, measurement design, numerical results, performance evaluation)

This course provides an extensive overview of the fundamental principles of wireless channels for radio communications/sensing. The course starts from the fundamentals of radio propagation and extends to the core techniques in radio system design to countermeasure against the dispersive radio channels.
The course includes an outlook over the most recent research developments in 5G/6G as well as an invited talk from an inspiring academic/industry figure.
Specific topics include:
- applications, requirements, challenges and opportunities of wireless communication/sensing systems;
- radio wave propagation mechanisms, multipath, deterministic description of wireless channels;
- large-scale path loss and small-scale fading;
- statistical description of wireless channels, including wideband and directional channel characterization;
- channel models;
- channel sounding/estimation techniques, diversity and equalization;
- Channel delay/range-Doppler-angular information.
