METHOD AND APPARATUS FOR CONTROLLING TRANSMIT POWER AND INCUMBENT PROTECTION IN A COGNITIVE RADIO SYSTEM

METHOD AND APPARATUS FOR CONTROLLING TRANSMIT POWER AND INCUMBENT PROTECTION IN A COGNITIVE RADIO SYSTEM

A cognitive radio (CR) device (208 and/or 218) avoids interference with an incumbent (207) receiver by determining maximum allowed transmit power levels of the CR device based on estimates of the incumbent signal level and transmit splatter levels of the CR device. The CR device (208 and/or 218) avo...

Zusammenfassung:A cognitive radio (CR) device (208 and/or 218) avoids interference with an incumbent (207) receiver by determining maximum allowed transmit power levels of the CR device based on estimates of the incumbent signal level and transmit splatter levels of the CR device. The CR device (208 and/or 218) avoids interference with the incumbent receiver while transmitting with maximum transmit power levels.
