【 摘 要 】

Spectrum sensing is one of the most basic technology of cognitive radio.Utilization of spectrum opportunity (USOP) is an important index of actual perception performance evaluation of the cognitive users.We analyses several factors that influence USOP,and proves the existence of optimal time perception which maximize USOP.When the transmission rate is 100 kb/s,the packet size is 500 bits,the false-alarm probability is 0.9,and the detection probability is 0.9,the calculated optimal spectrum perception of time is about 2 ms.
