摘要

摘要: 方向调制技术采用多天射阵列在天线端综合出具有方向特性的数字调制信号，是近年来物理层安全通信领域研究的热点之一。现有方向调制信号综合算法主要基于遗传算法和矢量法，但由于不同文献研究的通信系统模型不同，基于这两种算法的方向调制信号应用都具有一定的局限性。该文从窃听接收机所在的非期望方位接收方向调制信号星座点之间的相对相位关系产生畸变这一方向调制信号物理层安全本质出发，提出一种基于相位赋形的方向调制信号综合算法。首先根据不同的通信模型建立期望的相位波束空间覆盖函数，然后对期望的赋形相位波束采用空间傅里叶变换得到发射阵列的加权值。仿真结果表明该文提出的方向调制信号综合算法适用于笔形相位波束单用户信道、扇形相位波束的广播信道和多用户正交信道等不同的通信应用场景，为方向调制信号在不同通信场景中的应用提供技术支撑。

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.
