基于双层多参数加权类分数阶傅里叶变换的双极化卫星安全传输方案
|
摘要
为提高双极化卫星通信的安全传输性能,该文提出一种基于双层多参数加权类分数阶傅里叶变换(DL-MPWFRFT)的安全传输方法。该方法中对相互正交的两路极化状态-幅相联合调制信号进行DLMPWFRFT变换处理,并通过数模转换和射频化处理上载到卫星信道中。仿真结果表明,该方法使传输信号的星座图发生旋转和扩散,抗扫描能力提高,在增加系统容量的同时增强了系统的抗截获性。
In order to improve the secure transmission performance of dual-polarized satellite communication, a secure transmission method based on Double Layer Multi-Parameter Weighted-type FRactional Fourier Transform(DL-MPWFRFT) is proposed. Two orthogonally polarization amplitude-phase modulation branch signals are processed by DL-MPWFRFT, and then uploaded to the satellite channel by digital-to-analog conversion and radio frequency processing. The simulation results show that the method rotates and spreads the constellation of the transmitted signal, improves the anti-scanning capability, and increases the antiinterception performance of the system meanwhile increasing the system capacity.
