Objectives and outcomes
Students learn concepts and acquire knowledge of the analysis and design of modern mobile
communication systems. Moreover, they study the principles of contemporary transmission techniques in
these systems. Upon completion of the course, students identify and analyze the principles of
propagation fading (large-scale fading). They understand the effects of small-scale fading and multipath,
flat and frequency selective fading, fast and slow fading, Rayleigh fading, Rician fading. They apply
methods to mitigate the degradation effects of fading – linear, nonlinear and adaptive equalization.
Students know the techniques of diversity.
