Huang, Weiqing, Zhang, Qiaoyu, Wei, Dong, Li, Huiyan.  2019.  A Secure and Power-Efficient Constellations for Physical Layer Security. 2019 IEEE International Conference on Smart Internet of Things (SmartIoT). :479—483.
With the development of wireless networks, the security of wireless systems is becoming more and more important. In this paper, a novel double layers constellations is proposed to protect the polarization modulation information from being acquired by the eavesdropper. Based on the double layers constellations, a constellations' optimization algorithm for achieving high power-efficiency is proposed. Based on this algorithm, 4,8,16-order double-layer constellations are designed. We use Monte Carlo simulation to test the security performance and symbol error rate performance of this constellations. The results show that the double layers constellations can effectively ensure communication security and the SER performance has superiority over the classic symmetrical constellations.
