A generic model for MIMO wireless propagation channels

We study the MIMO wireless channel, and derive a generic channel model that we believe has the ability to explain all important effects, including (i) interdependency of directions-of-arrival and directions-of-departure, (ii) large delay and angle dispersion by propagation via far clusters, (iii) rank reduction of the transfer function matrix. We point out the relevant propagation effects, and propose a geometry-based model that includes the relevant effects. The required parameters for the complete definition of the model are enumerated, and typical simulation results for urban macrocells are presented
