Xue-Tao Dong, Mii Key · Communications technology · 2007
Cognitive radio can overcome spectrum scarcity problem by transferring fixed allocation strategy to dynamic strategy. Cognitive radio has novel function modules to support this transfer and thus result in many new entities and characteristics of the network. This paper analyzes the interference in space, time and frequency domain, finally discusses the transmit mode of the cognitive radio, and puts forward the further work as well.
