  • Spectrum usage databases for cognitive radio
    Patent number: 11361126
    Abstract: Access to data representations of relatively dynamic actual usage and patterns of spectrum usage across channels, geographies (locations), and times can be advantageous in planning for resource utilization, and in structuring pricing for spectrum resources. Actual usage of spectrum resources can vary dynamically. Significant opportunities to advantageously utilize spectrum resources can be identified from relatively dynamic representations of actual usage.
    Type: Grant

  • High dynamic range transceiver for cognitive radio
    Patent number: 8559891
    Abstract: Embodiments of cognitive radio technology can recover and utilize under-utilized portions of statically-allocated radio-frequency spectrum. A plurality of sensing methods can be employed. Transmission power control can be responsive to adjacent channel measurements. Digital pre-distortion techniques can enhance performance. Embodiments of a high DNR transceiver architecture can be employed.
