nonlinear separation based on MLP

说明：  】利用混沌动力学系统中logistic 映射先对水印图像进行置乱预处理以增强其鲁棒性, 在小波域中将原始音频信号按比例分段, 此比例为原始音频信号低频部分与水印信号个数之比, 然后将水印信号加入到音频信号的 低频部分。用StirMark 攻击后的实验结果表明, 该算法对StirMark 的部分攻击具有一定的鲁棒性。(The logistic- map sequences to encrypt the watermark are used. The original audio signal in DWT (Discrete Wavelet Transform) domain is seperated into some pieces determined by the ratio between the length of the low frequency parts and the length of the encrypted watermark. Every bit of the watermark is added into the relevant pieces of the low frequency parts in the DWT domain. Experimental results show that the algorithm is robust against some StirMark attacks.)

此函数是进行串并变化的功能函数，包含两个文件，一个进行提取基数为一个提取偶数位，从而达到串并变换的目的。这是在做需要多路进行数字调制所需要的步骤(This function is built to transform a sequence to serial and parallel sequence)

建立函数的最佳逼近程序，并且通过区间变换建立在任意区间的函数逼近(Establish the best approximation procedure of function, and establish the function approximation of arbitrary interval by interval transformation.)

说明：  这是在网上下的一个东东，很有用的，现在拿来和大家共享,是《参数估计和逆问题》的matlab程序(This is the Internet under a Dongdong, very useful, and we used to share, "parameter estimates and the inverse problem" Matlab procedures)
