ABSTRACT:
A cognitive radio (CR) device (208and/or218) 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 (208and/or218) avoids interference with the incumbent receiver while transmitting with maximum transmit power levels.
