Small tutorial of psim

low pass filter, this program can be to use how we can see a filter is worked

this is program of my project

source code for split and merge of image

基于分段非线性权重值的Pso算法，matlab程序，测试函数是griewank(sectionalized nonlinear weights based Pso algorithm, matlab program, the test function is griewank)

UPDATED CODE FOR SEGMENTATION FOR ULTRASOUND IMAGES

说明：  传染病模型是指传染病的基本数学模型，研究传染病的传播速度、空间范围、传播途径、动力学机理等问题，以指导对传染病的有效的预防和控制。常见的传染病模型按照传染病类型分为SI、SIR、SIRS、SEIR模型等。由于2019年末出现的新冠肺炎有一定的潜伏期，与病人接触过的健康人并不马上患病，而是称为病原体的携带者，归为E类。(infectious disease model simulation)

一、 本程序采用16QAM调制方式，对一串2进制信源进行调制，用升余弦滚降函数进行基带调制，再调到高频信道；在信道上加入高斯白噪声，运用匹配滤波器解调，画出解调星座图，运用最小欧氏距离译码判决，计算误比特率。(First, this program uses 16QAM modulation mode, for a string of two binary source is modulated with a raised cosine roll-off function for base-band modulation, and then transferred to high-frequency channel in the channel by adding Gaussian white noise, the use of matched filter device demodulator, draw demodulation constellation, using the minimum Euclidean distance decoding decision, calculate bit error rate.)

本人经过实际验证的比其他计算lyapunov指数更准确。。代码不足200行。。非常清晰明确(I read the actual verification than other lyapunov index calculation is more accurate. . Code less than 200 lines. . Very clear)
