| Abstract: | Location awareness for cognitive radios is studied,with a focus on the adaptive TOA(Time of Arrival) positioning technique.The decision criteria for positioning via underlay spectrum access is derived,and the ways to improve the success rate under underlay spectrum access positioning are proposed.Numerical results validate the derived decision criteria and the proposed measures. |
