基于labvieW的光纤光栅采集程序，使用了MOI公司的sm125解调仪。(FBG based labvieW collection procedures, the use of MOI' s sm125 demodulator.)

基频提取程序，已经运行成功，可以直接使用。(Fundamental frequency extraction procedure has been run successfully, can be used directly.)

说明：  加循环前后缀和升采样程序，插入循环前后缀是将每个OFDM符号的前32个数据放到符号尾部，将每个OFDM符号的后32个数据放到符号头部，升采样是通过中间插零的方式实现(Cycle before adding the suffix and lift sampling program, insert the loop before the suffix is ??the first of each OFDM symbol data into the symbolic end of 32, after each OFDM symbol data into the symbols of 32 head or through the middle of the sampling way to achieve zero insertion)

This project uses PCA (Principal Component Analysis) to detect face from 2D images.
