Abstract

This paper introduces a method for experimentally probing indoor wireless channels to compute MIMO transfer function matrices, H. The data is gathered using rotating transmit and receive antennas to observe the multipath ray structure of the channel. H can be computed for any arbitrary transmit and receive array sizes and geometries using the single probe data set. Estimating H is crucial for space-time coding communications algorithm performance analysis. Example results are presented
