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)

QAM
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.)
