摘要/Abstract

摘要： 加权分数阶傅里叶变换是一种新型物理层保密通信方式，可极大地提高通信系统的抗调制方式识别能力。针对单参数加权分数阶傅里叶变换易被破解的不足，提出一种基于时分数据调制的加权分数阶傅里叶变换通信方法。该方法采用奇偶位不同调制的策略，充分利用旋转因子动态加密，进行时分数据加权分数阶傅里叶变换调制，减弱信道中噪声对信号的影响，从而提高加权分数阶傅里叶变换调制信号的可靠性和安全性。仿真结果表明：基于时分数据调制的加权分数阶傅里叶变换调制信号，能够提高传统加权分数阶傅里叶变换信号的可靠性，显著降低窃听方的破译能力，可进一步增强信息传输的保密性能。

Abstract: The weighted fractional Fourier transform (4-WFRFT) is a new physical layer secret communication method, which can greatly improve the anti-modulation identification of the communication system. For the deficiencies of single-parameter weighted fractional Fourier transform, a time division modulation weighted fractional Fourier transform (TM-WFRFT) communication method is proposed. The proposed method adopts the strategy of different parity modulation and makes full use of the rotation factor to encrypt dynamically, so the security of the 4-WFRFT signal can be improved by time-division data weighted fractional Fourier modulation. The simulated results show that TM-WFRFT can significantly improve the 4-WFRFT reliability and significantly reduce the ability of the eavesdropper to decipher, thus improving the effectiveness of signal transmission and further enhancing the confidentiality of information transmission.
