THE SCHEME OF THE CLEAR CHANNEL SEARCH USING SPECTRUM SENSING IN 2.4GHZ ISM BAND AND THEREOF SYSTEM

摘要

PURPOSE: A method and a system for searching a clear channel in a communication environment are provided to search a clear channel with the least interference noise. CONSTITUTION: One or more wireless communication systems are selected among a plurality of wireless communication systems(S10). A wireless communication channel occupied by the selected wireless communication system is distinguished. A channel status map about the specific wireless communication system is configured under a communication environment based on information about a wireless communication channel occupied by the wireless communication system(S30). A clear channel about the wireless communication channel is selected based on the channel status map(S40).
