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.

通过在lmd中加入白噪声对信号进行分析，得出仿真图(through adding white noise in LMD to analyze the signal , get the simulation map)

隐马尔科夫树模型，这是一个自包含的程序包，包括2维离散小波变换和逆小波变换 例程。在每个子带中每个刻度的所有小波系数都绑在一起，避免了模型的过度拟合。(This is a self-contained package including the 2-D DWT and inverse DWT routines. All wavelet coefficients at each scale within each subband are tied together to avoid overfitting of the model. )
