T2F
T2F子函数,在做傅里叶变换时调用。我一开始编程序时忘了加它,结果WARN ME 说未定义T2F。(T2F subroutine, called when doing Fourier transform. I started to compile the program forgot to add it, and the result is undefined WARN ME said T2F.)

matlab_watermark
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.)

echo-cancellation
移动通信领域中已广泛采用自适应回波抵消技术,自适应回波抵消算法是该技术的核心,算法的优劣直接影响自适应回波抵消效果,同时它对降低硬件复杂度和产品成
本也有特殊意义。文章对自适应回波抵消的NLMS算法、双端讲话(DT)的检测算法及后
处理的NLP算法进行了分析和讨论。

lorenz
洛伦兹系统吸引子分岔图、最大李雅普指数、功率谱、时间序列等。其他系统只需改下系统方程(Lorentz system attractor bifurcation diagram, maximum Lyapu index, power spectrum, time series and so on. Other systems only need to change the system equation)

read-signal-sub-vi
可以直接读取txt格式的信号文件,一般是指振动波形数据。只需要输入目录和频率即可,出来就是波形图,该vi还对信号做了去直流的处理。(the vi can read the signal file which is writed in text formation。)
