Guardian: Co-site Interference Mitigation for VHF/UHF Communications

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 JTRS GMR for protection from co-site interference from sources such as co-located radios and jammers. Guardian can also improve power amplifier operation and reduce the interference levels across the network by allowing the transmitters to scale back the power they have to transmit to overcome co-site interference at the peer receiver. 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 was proven feasible in the Phase I study for the Navy application. In Phase II, Mayflower will develop and demonstrate a cost-effective Guardian prototype. In Phase III, Mayflower will ensure further development and commercialization of Guardian.
