numerical-approximation

随机时滞程序，用于种群模型、传染病模型数值模拟(The stochastic delay procedures for the population model, the numerical simulation of the epidemic model)

是一个自适应滤波器程序，用matlab编写，简单易用，大家试试哦(Is an adaptive filter program, written in matlab, easy to use, you try oh )

在matlab平台下产生信号序列通过QPSK方式调制通过高斯信道以及瑞利信道，对其中的过程的信号时域以及其频谱，星座图情况进行分析(Matlab platform in the signal sequence under way through the QPSK modulation, as well as through the Gaussian channel Rayleigh Road, on which the process of time-domain signal and its spectrum, constellation diagram analysis)

基于遗传算法BP神经网络优化的DIP控制(BP neural network based on genetic algorithm optimization DIP control)

这里面是信号与系统实验，比较适合于初学者，内容详细。(This experimental system, which is the signal and, more suitable for beginners and detailed.)

模拟2个独立窄带信号分别以20°，60°的方向入射到均匀线阵上，信号间互不相关，与噪声相互独立，噪声为理想高斯白噪声，阵元间距为入射信号波长的1／2，快拍数为200，信噪比为20dB，阵元数分别为10，50，100。 (Simulate two independent narrowband signals in the direction of 20 °, 60 ° of the incident on the ULA, among signal unrelated, independent noise, the noise is ideal Gaussian white noise, the array element spacing of the incident signal wavelength of 1/2, the number of snapshots 200, SNR is 20dB, the array element number 50, 100, respectively.)

QPSK在MATLAB平台上的调制与解调(QPSK modulation and demodulation)
