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 dynamic range transceiver architecture can be employed.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 : A method for sensing for cognitive radio comprising the steps of:
 receiving a first specified signal;   performing one or more first specified sensing functions,   wherein the one or more first specified sensing functions are at least partially responsive to the first specified signal;   performing one or more second specified sensing functions,   wherein the one or more second specified sensing functions are at least partially responsive to the first specified signal; and   determining a first sensing result,   wherein the first sensing result is at least partially responsive to the one or more first specified sensing functions and at least partially responsive to the one or more second specified sensing functions.   
     
     
         2 : A system for sensing for cognitive radio comprising:
 a first cognitive radio unit comprising:
 a first sensing element, 
 wherein the first sensing element provides one or more first specified sensing functions, and, 
 wherein the one or more first specified sensing functions are at least partially responsive to a first specified signal; and 
 a second sensing element, 
 wherein the second sensing element provides one or more second specified sensing functions, and, 
 wherein the one or more second specified sensing functions are at least partially responsive to the first specified signal; and, 
   wherein the first cognitive radio unit provides a first sensing result at least partially responsive to the one or more first specified sensing functions and at least partially responsive to the one or more second specified sensing functions.
