Modelling, analysis, and simulation of mobile-to-mobile MIMO channels
MetadataShow full item record
The development of mobile communication has been dramatically increasing in recent years. New concepts and methods are necessary for the improvement of existing mobile communication techniques due to the fact of the demand for these systems with higher data rates and a better quality of service. As the number of subscribers is growing rapidly, the development of mobile radio channel models has become one of the most important research topics within mobile communication systems. This thesis deals with a multiple-input multiple-output (MIMO) channel model for mobile- to-mobile communications. It starts with an analysis of a single-input single-output (SISO) channel model which is based on a geometrical street model under the assumption that the transmitter and the receiver are moving. Starting from the geometrical model, statistical properties of the analytical and simulation models will be studied. Of special interest are the probability density function, temporal autocorrelation function, Doppler power spec- tral density, level-crossing rate, and average duration of fades. Furthermore, the analytical results will be veri¯ed by MATLAB simulations. In the last part of this thesis the exten- sions of the SISO street model with respect to multiple clusters of scatterers, frequency selectivity, and to a MIMO street model are considered.
