Sammanfattning

We consider the clustering structure of wireless MIMO channels, and the impact that multiple clusters have on the performance of MIMO systems. We show that multiple clusters frequently occur in urban environments. We then proceed to demonstrate that a channel with multiple scatterer clusters behaves differently than a channel with one cluster and the same rms angular spread. The differences are quantified in terms of correlation coefficients, information-theoretic capacity, and interference-suppression capabilities. This demonstrates the necessity of correctly taking into account the clustering structure.
