BROADBAND BROANDBREAK LIMITATION SYSTEM WITH NEGATIVE GROUP PROPAGATION TIME AND BROADBAND BROADBAND REMOVAL METHOD

摘要

Embodiments of a broadband negative interference compensation (NGD) interference control (IM) system and a broadband interference suppression method are generally described herein. In some embodiments, the broadband IM limiting system may include a first frequency selection circuitry for capturing interfering signals within a bandwidth of interest, from a signal path. main signal, following the deletion of a desired signal, a deletion circuitry for implementing Negative Group Delay (NGD) on output signals from the first frequency selective circuit circuitry for generating negative group delay signals, and a second frequency select circuit arrangement for generating interference suppression signals from the negative group delay signals to be combined with signals from the main signal path. The negative group delay provided by the suppression circuitry may compensate for a group delay of the first frequency selection circuitry, a group delay of the second frequency selection circuit arrangement, and a group delay of the main signal path, so that the interference suppression signals have little, if any, group delay with respect to signals of the main signal path within the signal path; bandwidth of interest.
