The purpose of this course is to create an understanding of the radio channel behavior and characteristics and use these to analyze and evaluate various characteristics of wireless communication systems. Wireless communication systems are using the radio channel for transferring information. The radio channel properties therefore determine the opportunities and constraints that exist for the performance of wireless communication systems, but also what it is for example in radio-based positioning.

The course connects different areas of knowledge within, e.g., radio, digital communication, probability theory, stochastic processes, wave propagation and mathematics. The course covers the following topics: • Propagation Mechanisms - Free space propagation, reflection and transmission, diffraction, scattering phenomena, wave guiding • Statistical Description of the properties of wireless channels - The time-invariant two-path model, time-variant two-path model, small-scale fading with and without line-of-sight, Doppler spectra, level crossing rate and random FM, large-scale fading • Wideband Channel Characterization - Narrowband vs. wideband systems, system-theoretic description of propagation channels, the WSSUS (wide-sense stationary uncorrelated scattering) model, description methods for time dispersion, description methods for angular dispersion • Channel Models - Narrowband models, wideband models, spatial models, deterministic models, models for ultra wideband channels • Channel Sounding - Time-domain methods, frequency-domain methods, spatially resolved methods • Antenna aspects in wireless systems - Requirements for antennas in mobile radio, antennas for mobile stations, antennas for base stations, aspects of multiple antenna systems • Report writing - how do you author a scientific report in the area.
Undervisningsformer: Föreläsningar, övningar
Examinationsformer: Skriftlig tentamen, inlämningsuppgifter.
The performance assessment is based on the exam, which might be oral or written. To pass the course the assignment reports also have to be approved. The three assignments are to be solved in pairs of two students as independent work. These assignments include planning of measurements, performing the measurements, analysing the data and writing a report. Submission of all assignments is a requirement for participation in the exam.
