MIMO propagation channel modeling

Propagation channel models serve as input to MIMO system-level simulations. Present-day standard models capture the spatial domain by directions of arrival and departure of individual multipath components, and by the angular spread of clusters of such components. Fully polarimetric, sophisticated measurement campaigns have provided model parameters for a large number of wireless communication scenarios, including the statistics of these parameters. Challenges remain in the areas of interference modeling, of body-worn and sensor networks, of highly non-stationary channels, of diffuse scattering, and of over-the-air testing of MIMO terminals.
