一种振动信号频域处理方法，希望对大家有用(Vibration frequency domain signal processing method)

演示龙格库塔方法的绝对稳定区域，从1阶到4阶，且阶数可以调整。另外，区域的左右边界可以计算出来(Absolutely stable region demonstrates Runge-Kutta methods, from an order to the fourth order, and the order can be adjusted. Further, around the boundary region can be calculated)

FIR滤波器的频率抽样法,对照胡广书教师的教材例子进行了实现(FIR filter frequency sampling method,according to the example of Hu Guangshu s book《Digital Signal Processing》)

svd feature extraction

液压弹射的辅助计算程序，主要针对弹射的时间和受力大小分析(Auxiliary hydraulic catapult calculation program, mainly for ejection time and size of the force analysis)

Principal component analysis

低密度奇偶校验码一,简称码是当前通信领域的热门研究课题之一,是第四代移动通信系统强有力的竞争者。( A low-density parity check codes, referred yard is currently one of the hottest research topics in the field of communications, is the fourth generation mobile communication system strong competitor.)

电力电子的仿真，基础结构，适合原理讲解，初学者，包括：单极性PWM，双极性PWM，单相半波，单相半控，单相方波逆变，单相全控，斩波，三相半控，三相方波逆变，三相全控。文件名是对应的拼音。(Simulation of power electronics, infrastructure, suitable principle to explain, for beginners, including: unipolar PWM, bipolar Sexual PWM, single-phase half-wave, single-phase half-controlled, single-phase square wave inverter, single-phase control, chopper, three-phase half-controlled three Phase square wave inverter, three-phase full-controlled. The file name is corresponding to the alphabet.)

对双音信号的LUT基带数字预失真，功放采用saleh模型，附有各文件的组成说明。适合于深入学习功放线性化技术。该仿真对宽带和窄带都做了仿真，对窄带的效果更好，仍然有改进的余地。(This is a simulation program of Matlab for LUT digital baseband predistortion. It is helpful in learning High power amplifier linearity technology. Both of the narrowband and wideband situation is under simulation. The result shows that this shceme fits narrowband situation better.)

由混合信号分离出原信号的算法，目前比较成熟的线性盲源分离算法有很多，FastICA是其中之一。独立成分分析ICA是一个在多领域被应用的基础算法。ICA是一个不定问题，没有确定解，所以存在各种不同先验假定下的求解算法。相比其他技术，ICA的开源代码不是很多。(fast independent component analysis)
