分数阶傅立叶变换的各种程序，快速算法、线调频信号的处理等。

FRFT与PTS联合降低OFDM系统峰均功率比的方法-FRFT reduced OFDM system combined with the PTS PAPR method

稀疏分数阶傅里叶变换例子，线性调频信号的例子，分数阶傅里叶变换检测(Sparse fractional Fourier transform examples, linear frequency modulation signal example, fractional Fourier transform detection)

区别去传统的傅里叶变换，对于非平稳信号而言，分数傅里叶变换是一个较好的方法，本程序实现了分数傅里叶变化对LPF类信号的估计。具有较高的学习价值(Different from the traditional Fourier transform, for non-stationary signals, fractional Fourier transform is a better method, this program implements the fractional Fourier tran
