Innhold

A precise knowledge of mobile radio channels is indispensable for the development, evaluation, and test of present and future mobile radio communication systems. After all, from digital modulation techniques over channel coding to network aspects, nearly all relevant components of mobile radio systems are determined by the propagation characteristics of the channel. This course deals with the modelling, analysis, and simulation of mobile radio channels. It provides a fundamental understanding of many issues that are currently being investigated in the area of mobile radio channel modelling. Several classes of single-input single-output (SISO), and multiple-input multipleoutput (MIMO) fading channels are treated in detail. Furthermore, the description of efficient methods for the simulation of mobile radio channels is in the centre of attention. Specifically, the course will cover the following topics:

•  Review of random variables and stochastic processes

• Basics and methodologies of mobile radio channel modelling

• Fundamentals of stochastic and deterministic channel models

• Principles of sum-of-sinusoids and sum-of-cisoids models

• Frequency-nonselective channel models (Rayleigh channels, Rice channels, generalised Rice channels, Nakagami channels, various types of Suzuki channels, classical and modified Loo model.

• Frequency-selective channels (WSSUS models, DGUS models, COST 207 models)

• Geometry- and measurement-based MIMO channel models

• Modelling of Doppler, delay, and angular profiles

• Parametrization methods for the design of channel simulators

• Design of high-speed channel simulators

• Test and performance analysis of channel simulators

• Modelling and simulation of mobile-to-mobile channels

• Design of multiple uncorrelated Rayleigh fading waveforms

• Modelling and simulation of shadowing effects

• Modelling of frequency-hopping channels

• Design of bit and block error models.
