产生psk调制信号的源程序，并对信号进行成型滤波及上变频(generate PSK modulated signals, and the signals pass the shaping filter and DUC)

K-means++算法实现，加强了初始聚类点的选取（careful seeding）(K-means++ algorithm to enhance the selection of the initial clustering points (careful seeding))

基于小波分析的图像融合，采用的是系数加权平均法(Image fusion based on wavelet analysis, using the weighted average coefficient)

用matlab实现确定一个种子，然后检查它的近邻是否有相似性，把相似的都归到一个区域中。(Using matlab to determine a seed, and then checks whether its neighbors have similar similar property of a regional.)

输入信号为方波信号+高斯白噪声，方波信号基 频为1kHz，幅值为1，高斯白噪声方差为0.2， 均值为0，采样频率为20kHz。试用最大熵估计 法估计此信号的AR模型及其功率谱，并分析结 果(The input signal is a square wave signal+ Gaussian white noise, square wave signal fundamental frequency 1kHz, amplitude is a Gaussian white noise variance is 0.2, the mean is 0, the sampling frequency is 20kHz. Try maximum entropy estimation method to estimate the AR model of this signal and its power spectrum, and analyze the results)

说明：  removal of 50 hz noise (power line interference) from ecg signal using adaptive filtering

在层状光子晶体中，由于折射率不同，能量分布不同，此程序用于模拟此效果(Layered photonic crystals, due to the different refractive index, energy distribution, this procedure is used to simulate the effect of)

是画庞加莱映射的matlab程序，对初学者有很大的帮助，(Poincare map is painted matlab program, a great help for beginners,)

MATLAB中实现PID控制系统的，改变输入r(k）分别为阶跃信号、三角波、方波。(MATLAB to achieve PID control system, change the input r (k) are step signal, triangle wave, square wave.)

通过本实验，可以熟练掌握用MATLAB软件计算实际生活中的约束问题。(Through this experiment, you can master the use of MATLAB software to calculate real-life constraints.)
