调制识别是非协作通信中的关键技术之一，在电子对抗、软件无线电等领域 应用十分广泛。该过程介于信号检测与解调之间，由于对传输信号没有过多的先 验信息以及在接收端有很多未知的参数，例如：信号功率，载波频率和相位偏移， 时间信息等，导致对调制方式的盲识别是一项很困难的任务。此外，实际中存在 多径衰落、频率选择性和时变信道等问题，使得这项任务变得更具有挑战性。 (The modulation recognition is one of the key technologies of the non-cooperative communication, such as electronic countermeasures and software defination radio, therefore it is such a significant discipline and orientation in the research of communication field. Obviously, without enough knowledge in transmitter and verified parameters about receivers, for example signal power, carrier frequency and phase offsets and so force, it is hard to get the modulation of blind identification. What is more, for the sake of the multipath fading, frequency-selective and time-varying channels in the real scenarios the task is even harder. )

说明：  ant打包所需要的学习资料和相关配置，可以进行学习和本地搭建相关项目进行一切项目的编译和打包(ant but it the function is very good and strong)

整形规划-数值计算 Matlab 工具，可以用于科学计算，效果堪比 CPLEX-Plastic Planning - Matlab numericcal tools can be used for scientific computing, the effect of rivals CPLEX (Shaping planning- numerical Matlab tools can be used for scientific computing, the effect is comparable to the CPLEX-Plastic Planning- Matlab numericcal tools can be used for scientific computing Industries Integrated Service, and the effect of rivals CPLEX)

The additional argument (PeakD) is roughly the ratio of the typical peak width to the length of the entire data record. Small values detect fewer peaks larger values detect more peaks. It effects only the starting values for the peak detection parameters. (This is just a quick way to set reasonable initial values of the peak detection parameters, rather than specifying each one individually as in example 5.

matlab期望信号到达方向是0度，干扰方向20度，通过RLS算法画出波束成形的方向图(matlab desired signal arrival direction is 0 degrees, 20 degrees the direction of interference by the RLS algorithm to draw beamforming direction map)

说明：  隐马尔科夫模型（HMM）三大经典算法中的前向算法，通过输入HMM参数A,B,Pi矩阵以及序列O，可以计算该序列发生的概率(The forward algorithm in the three classic algorithms of Hidden Markov Model (HMM) can calculate the probability of occurrence of the sequence by inputting HMM parameters A, B, Pi matrix and sequence O.)

隐马尔科夫的源程序，主要用于模式识别中，也可用于其它(Hidden Markov source, is mainly used for pattern recognition can also be used for other)

提供了一种inverse gaussian分布定参的程序（程序中离散单位长度为1），R^2是统计量相关系数考虑了未知量的个数和拟合的精度。(Provided an inverse gaussian distribution of a given parameter of the program (in discrete units of length 1), R ^ 2 is a statistic correlation coefficient considering the number of unknowns and fitting accuracy.)
