PERCEPTION DETECTION METHOD AND SYSTEM BASED ON COGNITIVE RADIO SYSTEM

摘要

Disclosed are a perception detection method and system based on a cognitive radio system. The method comprises: according to a preset statistical strategy, determining at least one statistical time from the ending time of the previous perception detection time period to the beginning time of the next perception detection time period to perform statistics on a system performance; when the system performance meets the designated performance, comparing the time interval from the current statistical time to the beginning time of the next perception detection time period and a preset time interval; when the time interval from the current statistical time to the beginning time of the next perception detection time period is greater than and equal to the preset time interval, adjusting the beginning time of the next perception detection time period as the sum of the current statistical time and the time duration X; and re-determining the next perception detection time period by using the adjusted beginning time of the next perception detection time period, and performing perception detection in the re-determined next perception detection time period.
