code_3

OFEM接收机的解调，检测合格，效果良好，本人亲测(the demodulation of OFDM receiver)

说明：  改进的AR时间序列分析模型，加入了窗口的概念，源码里有实例(Improved AR time series analysis model, adding the concept of the window, there are instances where the source)

计算psnr，普通的4:0:0或者灰值图 有范围判断(calculate psnr format 4:0:0 or gray value picture judge for range)

说明：  如果能够把握其走向趋势，对于切削加工本身来说一定是一个不错的选择(Cutting force plays a very important role in machining in the 21st century. If we master its law, it is very useful for the accuracy)

附件中的m代码包括了一系列的拟合函数，这些函数通常的输入是概率分布的样本。还有最大似然估计仿真器、最小平方仿真器、混合高斯分布估计的EM算法、(M in the annex to the code, including a series of fitting function, which function normally is the probability distribution of input samples. There are maximum likelihood estimation simulator, emulator least squares, mixed-Gaussian distribution is estimated that the EM algorithm,)

代码中介绍了有文本如何转化为语音信号的方法，代码可以调试运行，效果良好(The code and introduces how the text into speech signal, the code can be debugged, good results)

又一个计算kalman滤波器的matlab程序！(Another calculation kalman filter matlab program!)

boost circuit for power electronics

数字通信中的锁相环（PLL）完整程序，包括噪声处理，可用于GPS的的跟踪和捕获(the matlab code of PLL ,including how to deal with the noise ,which can be used to acquiring and tracking on GPS)

经过调试过的朴素贝叶斯分类器，可以正常使用。(After debugging through the Naive Bayes classifier, can be used normally . )
