说明：  平滑滤波，自己写的小程序，希望对大家有所帮助(Filtering, write a small program, we want to help)

请用多层感知器（MLP）神经网络误差反向传播（BP）算法实现异或问题（输入为，要求可以判别输出为0或1），并画出学习曲线。其中，非线性函数采用S型Logistic函数。(Please use the Multilayer Perceptron (MLP) back propagation neural network (BP) algorithm XOR problem (input is required to determine the output is 0 or 1), and draw the learning curve. Among them, the non-linear function using S-type Logistic functions. )

MATLAB产生BPSK信号和FM信号。包括信号的成形滤波，频谱分析和功率谱分析(MATLAB generated BPSK signal and FM signals. Signal shaping filtering, spectrum analysis, power spectrum analysis)

此程序实现的是对一幅图像进行卡尔曼滤波实现多天线时变信道下基于卡尔曼滤波跟踪的数字图像通信系统仿真(Realize this procedure is the image of a Kalman filter to achieve multi-antenna time-varying channel tracking based on Kalman filtering of digital image communication system simulation)

基于copula函数求资产组合的风险VaR(Matlab copula VaR)

优化算法，用于多目标非线性函数在约束条件下的求解，经典算法simplex演变而来(Optimization algorithm for solving multi-objective nonlinear function under constraints, the classical algorithm simplex evolved)

本仿真程序实现了正交频分复用系统的调制与解调。(This program simulates orthogonal frequency division multiplexing（OFDM）system.)

使用变分EM方法实现的LDA文本模型 输入为文本即可 分解实现，含多个小函数可单独使用(LDA For Text Classification)

对调制信号的频谱进行估计，通过多径和高斯白噪声的信道，解调信号的频谱和输入信号相比较(Spectrum of the modulation signal is estimated by multi-path and Gaussian white noise channel, the demodulated signal of the spectrum and compare the input signal)

利用神经网络自校订、自学习功能在线整定PID(using neural network self-editing, self-learning function online tuning PID)
