Multi-user Directional Modulation Based on Polarization Transmission

In this paper, we proposed a novel multi-users directional polarization modulation (MUDPM) based on directional modulation and polarization modulation. The scheme can achieve security multi-users polarization modulation. The feasibility and security of MUDPM are evaluated in this paper. Moreover, we introduce a secure and precise transmission scheme. The scheme provides location-specific secure communication to legitimate users and the BER spatial distributions of the proposed scheme are analyzed via simulation.
