摘要

摘要: 方向調(diào)制技術(shù)采用多天射陣列在天線端綜合出具有方向特性的數(shù)字調(diào)制信號，是近年來物理層安全通信領(lǐng)域研究的熱點(diǎn)之一?，F(xiàn)有方向調(diào)制信號綜合算法主要基于遺傳算法和矢量法，但由于不同文獻(xiàn)研究的通信系統(tǒng)模型不同，基于這兩種算法的方向調(diào)制信號應(yīng)用都具有一定的局限性。該文從竊聽接收機(jī)所在的非期望方位接收方向調(diào)制信號星座點(diǎn)之間的相對相位關(guān)系產(chǎn)生畸變這一方向調(diào)制信號物理層安全本質(zhì)出發(fā)，提出一種基于相位賦形的方向調(diào)制信號綜合算法。首先根據(jù)不同的通信模型建立期望的相位波束空間覆蓋函數(shù)，然后對期望的賦形相位波束采用空間傅里葉變換得到發(fā)射陣列的加權(quán)值。仿真結(jié)果表明該文提出的方向調(diào)制信號綜合算法適用于筆形相位波束單用戶信道、扇形相位波束的廣播信道和多用戶正交信道等不同的通信應(yīng)用場景，為方向調(diào)制信號在不同通信場景中的應(yīng)用提供技術(shù)支撐。

Abstract: Directional Modulation (DM) technique is a hot research area for physical layer security communication in recent years. The baseband modulation signal is synthesized at the antenna level for transmitting different signal constellations at different directions. The genetic algorithm and vector method are the main synthesis algorithms for DM signal. However, these algorithms have some limitations for different communication models because of different research targets of these papers. In this paper, a DM signal synthesis algorithm based on phase beam-forming technique is proposed from the point view of that receive signal constellation of DM signal is scrambled at the undesired directions. First the phase beam function is set up for different communication models. Then the weighted values for array elements are obtained by the spatial Fourier transformation of the radiation pattern. Simulation results show that the proposed DM signal synthesis algorithm provides technological support for different communication models such as single user channel with pencil phase beam, broadcast channel with fanned phase beam and multi-access channel with orthogonal phase beam.
