In order to operate with maximum effectiveness in the combat zone, the warfighter depends on fast, clear and uninterrupted access to high-quality wireless signals for voice communications as well as command, control, targeting, and navigation information.
However, in highly contested and congested environments, intentional and unintentional interference can impact the wireless signal quality which affects the warfighter's effectiveness and endangers the safety of blue forces in the area.
Regardless of the origin of the interference, it is essential that tactical wireless systems have interference mitigation (IM) technology in order to maintain the high quality of wireless service that the warfighter demands.
Adaptive Dynamics Inc. (ADI) has been developing interference mitigation (IM) technology since 2003 and has developed a revolutionary digital signal processing (DSP) technology called ‘Multiple Adaptive Generalized Interference Cancellation’ (MAGIC™) that utilizes ELVES™ – a highly resource-efficient IP core with near-optimal performance for blind IM applications. MAGIC™ does not suffer from the disadvantages of the other traditional IM technologies and its performance has been independently verified in government labs with operational signal and interference waveforms.
We are proud to announce our selection as a 2018 TechConnect Defense Innovation Awardee.
