UHF SATCOM Wideband Interference Mitigation Navy SBIR FY2010.3 Sol No.: Navy SBIR FY2010.3 Topic No.: N103-230 Topic Title: UHF SATCOM Wideband Interference Mitigation Proposal No.: N103-230-0101 Firm: SA Photonics, LLC 130 Knowles Drive Suite A Los Gatos, California 95032-1832 Contact: Dave Pechner Phone: (408) 781-7416 Web Site: www.saphotonics.com Abstract: SA Photonics Diversity Interference Excision (DICE) system provides wideband interference cancellation for ground based MUOS terminals. DICE can excise multiple wideband and narrow band interferers in a completely blind fashion, without any knowledge of the signal of interest or interferers. DICE can be deployed as an Applique, or integrated into the front end of MUOS receivers. The software defined nature of DICE allows the same hardware to provide interference cancellation capabilities for existing UFO TACSAT terminals, providing immediate benefits today while maintaining a forward looking future proof design. Benefits: DICE offers a low cost, easy to use solution to the downlink RF satellite communication interference issue. By providing a completely blind adaptation process, no user interaction is required. The software defined architecture allows use against existing SATCOM terminals, while allowing a future proof design to eventual MUOS terminals. The system is designe solely with commercial off-the-shelf (COTS) components minimizing cost. Return
