在simulink中搭建Buck-Boost开环电路，但这种开环电路不好调整输出电压，于是又搭建了一种简单闭环电路(Buck-Boost open-loop circuit is built in simulink, but this open-loop circuit can not adjust the output voltage, so a simple closed-loop circuit is built.)

We formulate a scheduling problem that takes into account different hardware delays experienced by the secondary users (SUs) in a centralized cognitive radio network (CRN) while switching to different frequency bands. We propose a polynomial-time suboptimal algorithm to address our formulated scheduling problem. We evaluate the impact of varying switching delay, number of frequencies, and number of SUs. Our simulation results indicate that our proposed algorithm is robust to changes in the hardware spectrum switching delay and its performance is very close to its upper bound. We also compare our proposed method with the corresponding constant switching delay-based algorithm and demonstrate that our suggestion of taking into account the different hardware delays while switching to different frequency bands is essential for scheduling in CRNs.

该代码主要是实现自适应功能，用Matlab编写！(The code is mainly the realization of adaptive function, using Matlab to prepare!)
