garch-copula-VaR模型用于计算投资组合风险(garch-copula-VaR model is used to calculate portfolio risk)

三种方法实现数字下变频：直接法、bessel插值、多相滤波等(three method of DDC)

该函数实现标准的卡尔曼滤波算法，用于状态估计，目标跟踪(kalman filter)

kalman滤波方面的书籍，是一本经典的书籍。详细讲述了各种方法及组合滤波方法(kalman filter books, is a classic book. Detail the various methods and composition of the filter)

设计一维纳滤波器。 （1）产生三组观测数据，首先根据s(n)=as(n-1)+w(n)产生信号s(n)，将其加噪(信噪比分别为20dB，10dB，6dB)，得到观测数据x1(n)，x2(n)，x3(n)。 （2）估计xi(n)，i=1,2,3的AR模型参数。假设信号长度为L，AR模型阶数为N，分析实验结果，并讨论改变L，N对实验结果的影响。 (Design a Wiener filter. (1) generate three sets of observations data, first according to s (n) = as (n-1)+w (n) to generate a signal s (n), which add noise (SNR respectively 20dB, 10dB, 6dB), obtained observation data x1 (n), x2 (n), x3 (n). (2) estimate xi (n), i = AR model parameters 1,2,3. Assuming the signal length L, AR model of order N, analysis of experimental results and discuss changes affect L, N of the experimental results.)
