摘　　要：为了提高多用户方向调制的安全性能,利用信号极化特性,设计了一种基于极化传输的多用户方向调制方案。首先对多用户方向调制进行研究,再根据极化调制和多用户方向调制,对所提方案的信号进行设计,并通过理论推导,证明了所提方案的可行性和安全性。仿真结果表明,基于极化传输的多用户方向调制方案相比于传统的多用户方向调制方案,具有更窄的误码率波束宽度,且在期望方向上,窃听用户无法成功获得信息,进一步提高了多用户方向调制的安全性能。In order to improve the security performance of multi-user direction modulation,a multi-user direction modulation scheme based on polarization transmission is designed by using signal polarization characteristics.Firstly,multi-user direction modulation is studied.Then,according to the polarization modulation and multi-user direction modulation,the signal of the proposed scheme is designed.Finally,the feasibility and safety of the proposed scheme are proved by theoretical derivation.The simulation results indicate that the multi-user direction modulation scheme based on polarization transmission has a narrower error rate beamwidth than the traditional multi-user direction modulation scheme.In the desired direction,the eavesdropping user cannot successfully obtain information,which further improves the security performance of multi-user direction modulation.
