这本书不错，适合滤波器的学习用，程序已经调试通过。(This book is good for learning to use filters, testing procedures have been adopted.)

说明：  逻辑分析系统代码,在实验中广泛使用!放心用(Logic analysis system code, widely used in the experiment! Rest assured)

说明：  EM算法的相关程序，比较权威的，对大家学习有帮助(The related program of EM algorithm)

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.)

利用keyset进行遍历，它的优点在于可以根据你所想要的key值得到你想要的 values，更具灵活性！！ (Use keyset traversal of its advantages is that worth to the values ​ ​ you want the key you want more flexibility! !)

高斯拟合的应用，在曲线方面的应用，个人认为很有用(Gaussian fitting of the application, the application of the curve, think useful)

粒子群优化算法是一种进化优化技术，源于对鸟群扑食的行为，是一种基于迭代的优化工具。(PSO is an evolutionary optimization technique, derived the behavior of the birds of prey, is based on iterative optimization tools.)

用matlab来演奏张信哲的《过火》，比较有意思的一个程序(Matlab to play Jeff Chang' s " gone too far" , one of the more interesting program)
