Adaptive Dynamics, Inc. (ADI) has developed the MAGIC(TM) (Multiple Adaptive Generalized Interference Cancellation) Filter, a revolutionary interference mitigation technology that offers these specific advantages for both in band signal separation and out of band signal rejection: * It has demonstrated successful mitigation of multiple interference types (continuous wave (CW), swept tone, random FM, frequency hopped, etc.) to J/S levels exceeding 50 dB and provides out-of-band rejection greater than 70 dB. * The core algorithm is very well developed, and it is currently being applied to both narrow-band (5/25 KHz UHF MILSATCOM) and wideband (GPS, MUOS WCDMA, L-band FHSS) signals. * It is entirely a digital signal processing solution intended to function with a single antenna. * Its computing requirements are readily achieved with commodity COTS components suita-ble for the SWaP constraints. * It can be applied successfully as a low-cost retrofit filter module installed between the antenna and the radio. The Phase I project will conclude with a live demonstration using COTS hardware and our UHF SATCOM prototype.
