INITIALIZATION PROTOCOL OF MEDIUM ACCESS CONTROL LAYER FOR COGNITIVE RADIO SYSTEMS

摘要

present invention the use of intelligent cognitive radio wireless communication system (Cognitive Radio System, CR System) and for a communication initialization method (Initialization) in the MAC layer (Medium Access Control, MAC). Communication initialization process of the present invention detects the presence or absence of the frequency band used by the broadband and to minimize the sense of time that can occur at this time , and so as not to interfere with the existing communication system .
