signal+noise is very simple like this

一个主成分分析方法的matlab实现，比较经典齐全的源码(A matlab Implementation of principal component analysis)

计算时间序列的最大的里雅普诺夫指数的函数,(Calculation of time series The largest Lyapunov index in the function,)

signal modulation it is good for you

利用沈左右算子及直方图信息，提取目标区域的纹理特征。(Shen and histogram information about operator is employed to extract texture features of the target area )

that is the useful code to sove the example

对fastica工具箱进行了简化和程序的提取，增加了详细的注释。采用fastica算法的matlab程序，用以进行胎儿心电信号的提取。包含数据和程序，希望有用！！(Fastica toolbox to simplify and procedures of extraction, the detailed notes. Matlab program with fastica algorithms for the extraction of fetal ECG. Contains data and programs seek to help!!)

32个脉冲调制的线性调频连续波发射信号，单目标回波信号中加入了距离时延与多普勒频移信息。数字下变频后再进行脉压与MTD处理从而检测出距离与速度信息。(Chirp 32 pulse-modulated continuous wave transmit signals, a single target echo signal from the delay and added to the Doppler shift information. MTD frequency pulse pressure and then be processed to detect the distance and speed of digital information down.)
