A channel model for MIMO systems in macro- and microcellular environments

We consider the propagation in macro- and microcellular environments for systems with multiple antennas at both transmitter and receiver. We consider the important propagation effects that lead to (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 generic channel model that reflects those propagation effects, and propose different parameterizations of that model for macro- and microcellular environments. Cumulative distribution functions of the information-theoretic capacity derived from that model quantify the impact of the model on system design.
