zig-zag code for beginner

分析并实现了奇异谱斜率的方法，编程实现了时域信号的检测。(And to achieve a singular spectrum analysis method of slope, programming of the time-domain signal detection.)

法国人的emd算法，2007年的版本，镜像延拓，效果已经很不错了(French emd algorithm, the 2007 version, mirror extension, the effect is quite satisfactory)

说明：  功率谱 welch 方法 there is a simple demo for non parameteric spectral estimation methods(Welch method of power spectrum there is a simple demo for non parameteric spectral estimation methods)

可以实现对混合喜好的主分量分析，这是在盲信号处理中队信号的迁出里非常有用(likePCA)

蚁群算法！！！经典培训资料，建模必备！！！！！！！！！！(ACO! ! ! Classical training materials, modeling must! ! ! ! ! ! ! ! ! !)

The code gives an automatic solutions of simultaneous equations using gauss seidal elimination numerically. The equations must be inputted by the user accordingly.

matlab实现的DS-CDMA模块，功能齐全，适合使用(matlab cdma)

matlab仿真平台下仿真输出spwm的电压和电流模型(Voltage and current simulation model for spwm)

its an cdma transmiiter which is very easy and simple for beginners.
