Abstract

Embodiments of cognitive radio technology can recover and utilize underutilized 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.

Claims

1. A system for radio-frequency communications comprising:

a transceiver; and

,

a baseband processor comprising a sensing processor element,

a transmit power control element, wherein the transceiver is coupled with the baseband processor.
