matlab做的，关于滚动轴承振动信号故障诊断很重要的数据库，做机器学习的朋友可以看看啊！(Matlab do, on the rolling bearing vibration signal fault diagnosis is very important , machine learning friends can see ah!)

说明：  这是一个对比仿真实验： 基于复信号构造系统，生成IQ数据，进行QAM复调制，然后进行复解调，给出调制前后的频谱： 之后在用传统的载波调制的方式重新在做一遍，给出调制前后的频谱(This is a comparative simulation experiment: Based on complex signal construction system, IQ data is generated, QAM complex modulation is carried out, then complex demodulation is carried out, give the spectrum before and after modulation After that, the traditional carrier modulation method is used to do it again, give the spectrum before and after modulation)

利用BNT产生大量样本数据进行贝叶斯网络的结构学习与参数学习。(Use a large amount of sample data BNT structure learning and parameter learning Bayesian network.)

《MATLAB实用教程》 MATLAB例程源代码 可作为电子、通信、自控等专业本科生研究生及广大科研人员的参考。 (" MATLAB Practical Tutorial" MATLAB routine source code can be used as electronics, communications, self-control and other professional researchers undergraduate students and the general reference.)

Normalizes data between 0 and 1 (norm_RS1) or between -1 and +1 (norm_RS2)

C++实现数字信号处理中的DFT算法，不是快速算法，是基础DFT算法(C++ implementation of digital signal processing DFT algorithm, not a fast algorithm is the basis of DFT algorithm)
