Abstract :
We have developed an analogy between MIMO communications and inverse scattering to show that there is a close correspondence between the SNR behaviors of the communications channel capacity, effective degrees of freedom, and the quality of a reconstructed inverse image. These results have application to a MIMO configuration with coherently linked base stations, which can realize a capacity gain similar to standard MIMO but in a non-multipath propagation environment. It will be of interest to demonstrate this experimentally.
