摘要

摘要: 為提高雙極化衛(wèi)星通信的安全傳輸性能，該文提出一種基于雙層多參數加權類分數階傅里葉變換(DL-MPWFRFT)的安全傳輸方法。該方法中對相互正交的兩路極化狀態(tài)-幅相聯合調制信號進行DL-MPWFRFT變換處理，并通過數模轉換和射頻化處理上載到衛(wèi)星信道中。仿真結果表明，該方法使傳輸信號的星座圖發(fā)生旋轉和擴散，抗掃描能力提高，在增加系統容量的同時增強了系統的抗截獲性。

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.
