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 transform to estimate the class LPF signal. It has higher learning value)

信道为瑞利信道，S_D的距离为1米，三跳协作通信系统中S_R、R1_R1、S_D的距离均为1/3米。调制方式为BPSK,信噪比在-15dB-15dB间，接收端合并方式为ERC,迭代次数为1000(The channel is Rayleigh channel, the distance of S_D is 1 m, and the distance of S_R, R1, S_D in three-hop cooperative communication system is 1/3 M. The modulation mode is BPSK, the signal-to-noise ratio is between - 15dB and 15dB, the receiver merge mode is ERC, and the number of iterations is 1000.)
