pic 单片机上实现fft算法的相关资料 希望有所帮助-pic single chip to achieve fft algorithm would like to see the relevant information to help

匹配滤波器的实现。主要是通过fft变化使输出自相关最大，在通过滤波器。-Matched filter implementation. Mainly through changes in the output autocorrelation fft the largest through the filter.

介绍了离散傅里叶变换的原理，DFT,FFT,的相关内容，最后介绍的数字滤波器的原理及分类-Describes the discrete Fourier transform theory, DFT, FFT, relevant content, finally introduced the principle of the digital filter and classification
