- for finding 256fft using decimation in frequency
fftstepsense
- FFT algorithm used for Step sensing/detection for PIC MCU
PC-code-for-FFT
- this program calculates the twiddle factors, generator sine wave with user setting sample rate, signal frequency. The user interface gives parameter setting of sample frequency, signal freqency and number of sample and so on.
fft_design
- Very simple source code written in VHDL for FFT design.

- 主要用途是对抗多径衰落。由于多径衰落的存在，使得同一个帧由于路径不同，到达用户端的时延有先有后。在相关的频域上的会造成子载波之间的相互干扰，影响 性能。另外，由于有了循环前缀，使得IFFT FFT操作把原来的线性卷积变成循环卷积，大大简化了相应的信号处理复杂度
