Co-site Interference Mitigation for VHF/UHF Communications Navy SBIR FY2008.1 Sol No.: Navy SBIR FY2008.1 Topic No.: N08-093 Topic Title: Co-site Interference Mitigation for VHF/UHF Communications Proposal No.: N081-093-0026 Firm: Mayflower Communications Company, Inc. 20 Burlington Mall Road Burlington, Massachusetts 01803 Contact: William LeComte Phone: (781) 359-9500 Web Site: www.mayflowercom.com Abstract: Mayflower Communications Company, Inc. (Mayflower) proposes a co-site interference mitigation product, Guardian, to meet the Navy objectives, namely, develop and demonstrate techniques to mitigate the impact of unintentional interference in the VHF and UHF communications bands caused by high-power transmitters located in close proximity to the communicator. The proposed Guardian can be unobtrusively integrated with the radios such as SINCGARS, EPLRS and JTRS for protection from co-site interference, such as EW Jammer. Guardian functionality can also be incorporated in JTRS radios to reduce the interference levels across the network and in future EW jammers to solve the interference problem at the source. The proposed Guardian product leverages Mayflower's expertise in anti-jam, and builds on technology developed under several SBIR programs and Internal R&D. The Guardian co-site interference mitigation product, when proven feasible in the Phase I study for the Navy application, has enormous potential for military and commercial applications. In Phase I and Phase II, Mayflower will develop and demonstrate a cost-effective Guardian prototype. In Phase III, Mayflower will ensure further development and commercialization of Guardian. Benefits: The Mayflower Guardian product can protect friendly radio resources from crippling co-site interference and thereby solve vexing problems in modern urban and littoral combat. By solving the co-site interference problem without affecting radio functionality, Guardian can play an important and necessary role in enabling DoD net-centric warfare paradigm. The Mayflower Guardian product can also be used in commercial scenarios for co-site interference mitigation in large base station installations and for backbone full-duplex links. In both cases, co-site interference can be crippling and Guardian can play an effective role in mitigating this interference. Return
