Wideband analysis of indoor MIMO channels

The application of MIMO communication systems in real environments will invariably require systems to operate over wideband channels. Although suitable techniques for processing wideband MIMO channels have been reported, their evaluation has mainly been based on simulation using modelled channels. In this paper we investigate some of the properties of wideband MIMO channels and compare the characteristics of simulated channels with those measured in indoor environments at 5.2GHz.
