摘要
Abstract
The two important techniques in the understanding of the radio spectrum,perception and prediction is discussed.The system operating parameters are changed in real time adaptively according to certain learning and decision-making algorithms for the wireless communication environment for perception to dynamically detect and effectively use the free spectrum.Studies show that in theory multidimensional spectrum reuse in time,frequency and time is allowed,and thus the frequency spectrum and bandwidth constraints and the constraints on the development of the wireless technology are greatly reduced关键词
