Abstract

The characterization, modeling, and simulation of MIMO radio channels is fundamental for the design and evaluation of wireless MIMO systems. While flat-fading (narrowband) MIMO channels are quite well understood, the spatio-temporal-spectral structure of doubly dispersive MIMO channels still poses many problems. In this paper, we view these channels as multivariate WSSUS channels and use tools from (multivariate) spectrum analysis to assess their correlation in space/time/frequency. Our theoretical findings are supported by numerical results involving indoor MIMO measurements.
