摘　　要：通信作为重要的组成部分,提高其抗干扰性能具有极其重要的意义。文章首先建立系统干扰模型,其次阐述了分数傅里叶变换的基本原理,最后对基于分数傅立叶变换的调制解调方式与传统调制解调方式的误码率作对比,通过分析得出前者具有更好的通信抗干扰性能。As an important part of communication,it is of great significance to improve its anti-jamming performance.This article first establishes the system interference model,then the basic principle of fractional fourier transform is expounded.Finally,the bit error rate of modulation and demodulation based on fractional fourier transform is compared with that of traditional modulation and demodulation.The former has better communication anti-interference performance.
