High Spectrum Efficiency Technologies

Radio spectrum is a scarce and therefore valuable commodity. There is a growing need in both government and commercial sectors to make more efficient use of the available spectrum to serve greater densities of users as well as support higher data rates. Not only has demand for spectrum exponentially increased in recent times, but spectrum currently allocated to DoD users is being reallocated for commercial applications, putting a premium on network area spectral efficiency in both commercial and military applications. We will investigate techniques that dynamically select network topologies, message routings, and frequency assignments to maximize network area spectral efficiency by minimizing interference. A major challenge is to identify means of achieving this optimization without resorting to centralized control from an omniscient node.
