摘要：
Different from the MAC of IEEE 802 11, the application of IEEE 802 22 suffers the uncertain spectrum and frequency width, which can not ensure the access of mobile users to be valid To sole the problem, in this paper, we modify the CSMA/CA mechanism in order to make it suit the Cognitive Radio environments, in which the spectrum can be effectively used We validate the modification by numerical analysis
