ORB Analytics — Department of Defense SBIR Phase I: To achieve dramatic gains in spectrum efficiency over current military wireless communicat

Description

To achieve dramatic gains in spectrum efficiency over current military wireless communication networks, ORB Analytics proposes an intelligent overlay network built of Cognitive Radios (CR) that exploit multi-domain information including geo-location, modulation, policy, and historical usage information for primary users as well as other CR nodes. Such information can be efficiently architected using a radio environment map (REM). Harnessing this REM along with node clustering to reduce complexity, sophisticated techniques at all levels of the communications protocol stack can be constructed to efficiently multiplex through time, frequency, and space while avoiding legacy PU networks. Such techniques include multi-user MIMO spatial multiplexing, multi-user detection, adaptive modulation and coding, adaptive scheduling, and smart routing. The overall design of this next generation network will produce a dramatic leap in spectrum efficiency over current networks.
