通信调制中的FSK调制，用4个不同的调制载波对发送信号进行调制，从而代表不同的信息(four carriers fsk)

计算复合材料的基本物理性能参数,包括弹性模量，泊松比，密度，热导率，热膨胀系数(Calculation of the basic physical parameters of composite materials )

增广最小二乘的递推算法对应的噪声模型为滑动平均噪声，扩充了参数向量和数据向量H（k）的维数，把噪声模型的辨识同时考虑进去。最小二乘法只能获得过程模型的参数估计，而增广最小二乘法同时又能获得噪声模型的参数估计，若噪声模型为平均滑动模型，，则只能用RELS算法才能获得无偏估计。当数据长度较大时，辨识精度低于极大似然法。(Augmented least squares of recursion algorithm corresponding noise model for moving average noise, expanded parameter vector and data vector H (k) of the dimension, the noise model identification and at the same time into consideration. Least square method can only obtain process model parameter estimation, and augmented least squares method at the same time can obtain noise model parameter estimation, if noise model for the average sliding model,, it can only use RELS algorithm to obtain unbiased estimation. When the data length is bigger, the identification accuracy is lower than maximum likelihood method.)

均值滤波：把每个像素周围的8个像素来做均值操作，可以平滑图像，速度快，算法简单，但是无法去掉噪声，只能微弱的减弱它。(The mean filtering: 8 pixels around each pixel do mean, you can smooth image, fast and simple algorithm, but can not get rid of the noise, only faint weakened it.)

用聚类谱算法进行信号处理，含实测数据，亲测过，很好用(Spectral clustering algorithms with signal processing, including measured data, pro-test too, the good)
