摘要

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DL-MPWFRFT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。

Abstract: 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 anti-interception performance of the system meanwhile increasing the system capacity.
