时域信号转换为频域信号的几个例子，本人都用过的，绝对能运行(Time-domain signal is converted to frequency domain signal a few examples, I have been used, absolutely can run)

MEL FREQUENCY CEPSTRAL COEFFCIENT

我学习信号系统时原创的用matlab实现的谐波提取 ，两种方案，先分频再提基波，或者利用带通滤波器(I study the signal system to achieve an original harmonic extraction using matlab, the two programs, the first frequency and then Ti Jibo, or the use of band-pass filter )

说明：  介绍matlab和vc混编后独立运行程序(Introduce matlab and vc after running the program. Independent mix )

Timpul dat, face referire la selectarea timpului in functie de alegerile facute, simplu si usor de utilizat

光纤相干通讯数字相干接收机，算法和子系统。一篇很精简全面的总结。(Digital coherent optical receiver algorithms and subsystems in fiber coherent optical communication. A very good brief summary.)

用来描述铁电存储器MFIS-FET结构的C-V（即电容-电压）关系(Used to describe the ferroelectric memory MFIS-FET structure of CV (ie capacitance- voltage) relationship)

该软件包详细给出了字母识别的程序代码及训练字符，对有用到这方面的朋友会很有帮助。(Details of the package gives the letter code identification and training of character, to be useful to the friend would be helpful in this regard.)

线性四面体元的有限元分析可直接利用的函数，包括求刚度矩阵，求体积，求整体刚度矩阵等，有重要的利用价值(Linear tetrahedral element finite element analysis can be directly used for functions, including seeking stiffness matrix, the volume demand, the global stiffness matrix of such demand, there is significant value in use)

卡尔曼滤波源程序，比较实用，在matlab环境中编写！(EKF/UKF kalman)
