摘要：
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.
