混凝土配合比计算程序。可根据混凝土强度得到配合比。自己编的。参考规范为2009年之前的规范。(Concrete mix calculations. Be in accordance with the ratio of concrete strength. Their series. Reference standard for the specification by 2009.)

This the program for Generalized synchronization of fractional order Hyperchaotic chen system

说明：  未编码传输AWGN信道测试 每帧的输入是相同的，（不是每帧都不一样，这样可以大幅降低计算量） 在帧比特足够多的情况下，应该可以保证随机性(AWGN channel is not coded transmission test input of each frame is the same, (not every frame is different, this can significantly reduce the computation) are enough bits in the frame of the case, should be able to guarantee randomness)

能够非常清楚的看出幅值和时间的变化规律，不用再画时、频图(Can very clear indication of the amplitude and the change of time rule，Don t draw, frequency chart)

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)，将其加噪声(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) produces three sets of observations: First, according to S (n) = aS (n-1)+ w (n) generates the signal S (n), to add noise (SNR are 20db, 10db, 6db ), obtained observational data X1 (n), X2 (n), X3 (n). . (2) estimated Xi (n), i = 1,2,3 of the AR model parameters. Assuming the signal length L, AR model order N, the analysis of experimental results, and discuss the changes in L, N to the experimental results.)
