摘要：
In cognitive radio (CR) networks, cognitive users need to continuously monitor spectrum to detect the presence of primary users, yet attain a reasonable throughput In this paper, we exploit a scheme to detect the primary transmitting signal as quickly as possible using energy detection, besides a necessary transmission rate of CR networks is sustained. Also the relationship between time and frequency sensitivity In spectrum detection is given, whose product is a function of effective receive signal to noise ratio (SNR) of CR user.
