Enabling LPI/LPD single-frequency full duplex for tactical communication systems

The goal of this proposal is to enable improved tactical networks based on single-frequency full duplex communication systems. GenXComm has developed a unique physical layer that enables wideband, tunable interference cancellation. This physical layer forms the foundation for the MAC and routing designs in this proposal. We propose to use single-frequency full duplex to enable tactical systems through intelligent frequency hopping with post-synchronization, adaptive access strategies based on jamming patterns and reduction in latency through cut-through routing. Combined, these strategies enable LPI and LPD in a tactical network by ensuring better coordination between nodes, significantly better resilience to jamming, and the ability to self-jam the medium without suffering from the resulting interference. This, combined with reduction in latency due to routing strategies such as cut-through will result in significant overall performance improvements in SWaP and efficiency in addition to strategic gains for the Army's tactical networks.
