Description In this paper a novel decomposition of spatial channels is developed to provide insight into spatial aspects of multiple antenna communication systems. Free space propagation is used to model the channel in scatterer free regions around the transmitter and the receiver, and the rest of the complex scattering media is represented by a parametric model. We show that the channel matrix of a MIMO system can be factored into fixed (and known) and random matrices where the deterministic portion depends on receiver and transmitter antenna configurations. We use the model to show the intrinsic degrees of freedom in a multi-antenna system. Potential applications of the model are briefly discussed.
