Highly Flexible Active Notch Filter For Cognitive Radio
Résumé
Nowadays, many wireless communication devicesshould share the precious radio-frequency bandwidths. In orderto get the most of the available spectrum, Cognitive Radio (CR)are recently introduced to allow better spectrum management fornewly standardized radio communication systems. An advancedmultistandard terminal device may cover several communicationstandards. The system of such device should be highly flexible todynamically and autonomously adjust its radio operatingparameters. Moreover, the reduction of interference among radiocommunication systems is needed to allow the coexistence ofdifferent standards in the same device. In this paper, a newconcept and system architecture to reach our goal are proposedand discussed. Our ultimate goal aims to ensure the coexistenceof different standards in a CR mobile terminal.
