Pd-SNR

说明：  该程序用matlab编写的，采用crosstrain方法进行模式识别的方法。(the procedures used in the preparation of Matlab, crosstrain using the method of pattern recognition methods.)

信号为两个正弦信号加高斯白噪声，各正弦信号的信噪比均为10dB，长度为N，信号频率分别为 和 ，初始相位 ，取 ， 取不同数值：0.3，0.25。 为采样频率。分别用Levinson递推法和Burg法进行功率谱估计，并分析改变数据长度、模型阶数对谱估计结果的影响。(Signal into two sinusoidal signals applied Gaussian white noise, the SNR of each sinusoidal signals are 10dB, a length of N, respectively, and the signal frequency, initial phase, take, take different values: 0.3,0.25. It is the sampling frequency. Respectively Levinson recursion method and Burg method for power spectrum estimation, and change the length of the data analysis, the impact of model order estimation result spectrum.)

COPULA to simulate a speckle pattern

说明：  该算法可以实现遗传算法优化计算中的建模自变量降维方法(Genetic Algorithms for Optimizing Computation-Modeling Independent Variables for Dimension Reduction)

通过这个实验，熟悉并能够灵活运用插值函数的方法去解决实际生活中的问题。(Through this experiment, familiar and flexible use of interpolation functions to solve real life problems.)
