该matlab程序源码主要实现单个认知用户频谱感知敏捷性的最优化，其基本的感知环节采用能量检测法；在恒漏检准则下，感知敏捷性可以用平均的感知时间来衡量；达到平均感知时间的最小化，也就实现了感知敏捷性的最优化。-The matlab main program source code to realize the optimization of single user spectrum sensing agility, its basic perceived links using energy detection method　in the constant detection criterion, the perception of agility can be used to measure the average time perception　minimize average sense of time, can achieve the optimal sensing agility.
