METHOD FOR ADJUSTING CHANNELS IN COGNITIVE WIRELESS COMMUNICATION, AND COGNITIVE WIRELESS COMMUNICATION SYSTEM CAPABLE OF IMPLEMENTING THE METHOD

摘要

This invention is directed to provision of a channel adjusting method capable of suppressing the occurrence of interference between a cognitive pilot channel (CPC) and an auxiliary control channel (ACS) in cognitive wireless communications. According to the inventive channel adjusting method for use in cognitive wireless communications, initially, a connection using a cognitive pilot channel (CPC) is set up. Thereafter, it is determined whether or not a spectrum sensing channel (ACS) is to be utilized. If yes, it is then determined whether or not any interference occurs between the spectrum sensing channel (ACS) and the set-up cognitive pilot channel (CPC). This allows an adjustment to be performed such that no interference occurs between the cognitive pilot channel (CPC) and the spectrum sensing channel (ACS).
