Abstract :
A spatial-temporal channel simulator is necessary for properly designing, analyzing and implementing multi-antenna systems. A new geometry-based spatial-temporal channel simulator is proposed; it assumes that double bounce scattering components are the dominant multipaths received by base station and mobile as well as single bounce scattering components. Considering that scatterers from different distances to a mobile influence signal propagation dissimilarly, two different scatterer distribution densities within the coverage area are applied. Comparison of an example of urban channel simulation with measurement results shows that the simulator is capable of characterizing most of the properties of an urban channel. The simulator can also be configured to meet different requirement of angle spread and delay spread for estimating the robustness of a multi-antenna system.
