起伏地表下的地震波场数值模拟，有限差分法，一层介质，人工吸收边界条件，求取时间波场快照(Numerical simulation of seismic wave fields, finite difference method, a layer of dielectric undulating surface under artificial absorbing boundary conditions, the time to strike a snapshot of the wave field)

this is a matlab program for a feedback and control systems laboratory subject

说明：  用双线性变换法设计一个Butterworth低通滤波器，要求其通带截止频率100Hz，阻带截止频率200Hz，通带衰减小于2dB，阻带衰减大于15 dB，采样频率为500 Hz。(Using bilinear transformation to design a Butterworth low-pass filter, requiring that their pass-band cutoff frequency 100Hz, stopband cutoff frequency 200Hz, pass-band attenuation is less than 2dB, stop-band attenuation greater than 15 dB, a sampling frequency of 500 Hz.)

在matlab环境下对泊松过程的模拟检验和参数估计(Poisson process in matlab simulation, testing and parameter estimation)

this project simulates cdma network using 63 gold code and rake receiver.then, compares performance with multi-carrier-cdma method.

人提供了一种小波去噪和小波包去噪的对比研究的matlab代码，供大家相互学习和参考(Provide a comparative study of wavelet de-noising and wavelet packet denoising matlab code for everyone to learn from each other and reference)

说明：  有关随机有限集一阶矩PHD和粒子滤波相结合的matlab实现的程序，对于学习PHD和粒子滤波有一定的帮助！(First moment PHD filter matlab implementation procedures for random finite set.)

希望给辛苦科研的人带来一点点帮助--学习因子可以变化的PSO算法，不再是c1=c2=2，粒子进化更加灵活，下面是学习因子同步变化的pso，调用形式为[xm,fv]=LNCPSO(fitness,N,cmax,cmin,w,M,D)(People who want to work hard to bring a little bit of research to help- learning factor can vary PSO algorithm is no longer c1 = c2 = 2, particle evolution is more flexible, learning factor is below synchronous changes pso, calling in the form of [xm, fv] = LNCPSO (fitness, N, cmax, cmin, w, M, D))
