GIRD has an extensive background in the field of adaptive interference mitigation. Using signal processing techniques, noise from a variety of sources can be reduced or eliminated. Applications in this area range from mobile telephone transmission noise to interference in biomedical instruments and systems.

Adaptive signal processing is used to automatically remove interference and noise from corrupted signals electronically. GIRD personnel have extensive experience with audio, ultrasonic, and RF noise/interference cancellation and excision. One example is proprietary work GIRD performed for Ethicon Endo-Surgery, a subsidiary of Johnson & Johnson, on interference mitigation in a biomedical instrumentation system. GIRD has also recently started a Phase II SBIR program to develop novel interference mitigation algorithms and hardware for Navy SPAWAR on MILSATCOM channels.
