摘 要:单质通信信号的干扰抵消在一定程度上可以确保数据信息的安全收发,因此将重点研究基于稀疏傅里叶变换的电子通信干扰抵消方法。先对强干扰通信信号进行预处理,再设计信号干扰抵消频谱,然后构建稀疏傅里叶分段式变换干扰抵消模型,并采用逆向载波法实现电子通信干扰抵消。测试结果表明:与传统中强通信干扰抵消测试组、传统有线传输通信干扰抵消测试组相比,基于稀疏傅里叶变换的通信干扰抵消测试组得出的抵消信噪比相对较高,说明在对电子通信信号干扰抵消的过程中,抵消叠加误差较小且保持恒定,具有重要的通信应用价值。To a certain extent,the interference cancellation of single-substance communication signals can ensure the safe transmission and reception of data information.Therefore,an electronic communication interference cancellation method based on Sparse Fourier Transform is studied.The strong interference communication signal is preprocessed,the signal interference cancellation spectrum is designed,the sparse Fourier segmented transform interference cancellation model is constructed,and the inverse carrier method is used to realize the electronic communication interference cancellation.The test results show that compared with the traditional medium-strong communication interference cancellation test group and the traditional wired transmission communication interference cancellation test group,the designed Sparse Fourier Transform communication interference cancellation test group has a relatively high cancellation signal-to-noise ratio,indicating that In the process of canceling the interference of the electronic communication signal,the offset superposition error is small and constant,which has practical communication application value.
