Abstract-- In this paper a novel three dimensional spatial
channels model is developed to provide insight into spatial as-
pects of multiple antenna communication systems. The spherical
harmonic representation of wavefields is used to decompose the
spatial channel matrix into a product of known and random
matrices where the known portion shows the effects of the
physical configuration of antenna elements. The model supports
any arbitrary antenna array configurations as well as any
distribution of scatterers. Possible applications of the model and
its usefulness are outlined.
I. INTRODUCTION
Multi antenna element wireless communications systems
have shown significantly large capacity gains compared to
traditional single input single output systems [1], [2]. However,
recent results [3], [4] indicate that such large gains are
