中频70M，30M带宽LFM信号，采样率为102.4M，数字下变频后，还进行了三倍抽取，最后还得到I，Q两路信号 (IF 70M, 30M bandwidth LFM signal, the sampling rate of 102.4M, digital down conversion, the samples were carried out three times, the last also I, Q two-way signal)

关于线性方程组迭代法的源代码，matlab编写的，值得收藏，欢迎大家踊跃下载，为中国的科研事业做贡献(Linear equations about the source code of iteration method, matlab prepared and worthy of collection, enthusiastically welcomed the U.S. download, in order to make China' s contribution to the cause of scientific research)

对数据进行emd分解，可以自适应得到对应的模态分量(Emd decomposition of the data can be adaptive to get the corresponding modal components)

说明：  文章：利用三次样条函数计算开挖体积，有matlab代码。(Article: the use of cubic spline function calculated excavation volume, there is matlab code.)

kground: Abnormally high CSF 3-OMD occurs frequently for RLS patients indicating either increased L-dopa synthesis, limitations in L-dopa decarboxylation or increased MAT/COMT activity, or some combination of these. Increased tyrosine hydroxylase activity was found on both the RLS autopsy and the rodent iron-deprivation model of RLS, suggesting increased DA synthesis in RLS. We, therefore, hypothesized elevated 3-OMD in RLS results from increased DA synthesis and that this should occur accordingly with increased HVA. It would then also reflect both the more severe iron insufficiency pathology of RLS and greater clinical severity, shown by the objective measure of PLMS/hr. Methods: Patients off RLS medications and matched controls had

this file is matlab code for hunting search algorithm.i think it can be so useful.thanks

高阶循环累积量对信号进行识别，该文件代码完整，适合学习，可以直接更改来识别信号(Order cyclic cumulants of the signal recognition, the document code integrity, for learning, you can change to identify the signal directly)

本文算法是将24 位真彩图的亮度分量分块 DCT ,然后利用DCT 量化系数的奇偶特性嵌入8 位灰度水印图,并通过PN 序列加密来保证水印的 安全性。算法中,将灰度图像转换为二进制数据 流,置乱后扩频调制,隐藏在宿主DCT 系数量化值 中,提取时不需要宿主信号,实现水印信号的盲提 取。(This algorithm is 24-bit true color pictures of the luminance component of block DCT, quantization DCT coefficients and then use the parity properties of 8-bit grayscale watermark embedding map, and through the PN sequence of encryption to ensure the security of the watermark. Algorithm, the gray image into binary data stream, scrambling after the spread spectrum modulation, hidden in the host DCT coefficient quantization values, the extraction does not require the host signal, the blind watermark extraction.)
