Abstract
The disclosure provides a method and a device for controlling power of a cognitive radio system. The method comprises: measuring a system parameter of a cognitive radio system and a system parameter of a TV system located in an adjacent channel of the cognitive radio system; determining a maximum transmission power of the cognitive radio system according to the system parameter of the cognitive radio system and the system parameter of the TV system; controlling an actual transmission power of the cognitive radio system to be less than the maximum transmission power. In the disclosure, interference to the TV system can be reduced maximally, so that the sensitivity of a receiver inside the TV system is guaranteed.
