认知无线电功率控制算法中各认知用户最小发射功率的计算(Calculation of each cognitive user minimum transmit power in cognitive radio power control algorithm)

matlab编的可以画吸收光谱的程序，数据需要手动修改输入，从oring粘贴就行(the program could be used to draw the absorption of uv visible,the results of Gaussian.The data should be changed by hand.)

最小二乘支持向量机，程序粘到command window里，设定 2 两个参数，可以更改，以达到最优化(igam=0.001 isig2=0.001 [gam,sig2]=tunelssvm({X,Y, f ,igam,isig2, RBF_kernel },... [0.001 0.001 10000 10000], gridsearch ,{}, leaveoneout_lssvm ) type= function approximation kernel= RBF_kernel model=initlssvm(X,Y,type,gam,sig2,kernel) model model=trainlssvm(model) Yt=simlssvm(model,Xt) )

正弦信号产生一个具有两个正弦信号向量，本设计中运用continuous-state space s-function模块对输入信号进行变换，并通过scope模块显示出来。压缩文件中提供了M文件s-function的编写，以及搭建的模型框图(Generate a sinusoidal signal with two sinusoidal signal vector, the design of the use continuous-state space s-function module to transform the input signal and display module through the scope. Zip file provided in the file s-function M in the preparation and structures of the model diagram)
