四相绝对相移键控的仿真和分析，四个图形合成，有意思(Four-phase phase-shift keying absolute simulation and analysis, four graphics synthesis, interesting)

可以用于计算排列熵，很实用，欢迎大家交流(Arrangement can be used to calculate the entropy, it is practical, we welcome the exchange of)

说明：  自编：张贤达《数字信号处理》习题4.26的MATLAB程序。加入了一个GUI界面。 在MATLAB下运行MDSP。 要求MATLAB7以上版本，否则GUI无法运行(self : Automation, "Digital Signal Processing" Exercise 4.26 MATLAB. Adding a GUI interface. MATLAB running MDSP. MATLAB7 version of the above requirements, otherwise unable to run GUI)

对matlab工具箱中的多元逐步回归算法参数表现更明确(Matlab toolbox to the stepwise multiple regression algorithm performance parameters more clearly)

编写一个含QAM传输的发送和接收模块 1)分别采用复基带仿真和实带通仿真两种形式 a) 实带通仿真时, 载波频率为符号率的4倍 b)发端采用滚降系数0.5的根号升余弦滤波器 2)画出Eb/N0=15dB时的接收波形(收滤波前),取100个采样 3)画出发端输出的眼图和收端过匹配滤波后的眼图(画眼图时不加噪声) 统计误符号率和误比特率与Eb/N0的关系,画出曲线, 与理论计算的曲线相对比 (Prepare to send of one with QAM transmission and receiver module 1), respectively, the complex baseband simulation and the real band-pass simulation in two forms a) the real band-pass simulation, the carrier frequency used for the symbol rate of 4 times b) the originator roll-off factor of 0.5 root raised cosine filter, 2) draw Eb/N0 = 15dB when the received waveform (closing filter), take 100 samples) to draw the originator of the output eye diagram and income side of the eye diagram after the matched filter ( draw the eye diagram without noise) statistics symbol error rate and bit error rate and Eb/N0, draw a curve calculated with the theoretical curve compared)

相似度算法的实现， 在利用支持向量机进行模式分类的时候，有时需要考虑到实时性，为了提高实时性，则利用相似度算法减少样本集个数，从而减少训练时间和支持向量的个数，使得建立起的向量机实时性提高。(Similarity algorithm, support vector machine in pattern classification, it is sometimes need to take into account the real-time, in order to improve real-time, the use of similarity algorithm to reduce the number of sample collection, thus reducing training time and the number of support vectors， improve the real-time of established Vector Machines.)
