Abstract:

This paper derives a generic model for the MIMO wireless channel. The model has the ability to explain 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 propose a geometry-based model that includes the propagation effects that are critical for MIMO performance: (i) single scattering around the BS and MS, (ii) scattering by far clusters, (iii) double-scattering, (iv) waveguiding, and (v) diffraction by roof edges. The required parameters for the complete definition of the model are enumerated, and typical parameter values in macro- and microcellular environments are discussed.
