Title: Phase-Array transmission for Secure mmWave Wireless Communication via Polygon Construction
Two secure transmission algorithms for millimeter-wave wireless communication will be presented. The presented algorithms are computationally attractive and have analytical solutions. In the proposed algorithms, we consider phased-array transmission architecture and focus on PSK modulation. It is found that the traditional constellation synthesis problem can be solved with the aid of polygon construction in the complex plane. A detailed analysis is then carried out and an analytical procedure is developed to obtain a qualified phase solution. For a given synthesis task, it is derived that there exist infinite weight vector solutions under a mild condition. Based on this result, we propose the two secure transmission algorithms by varying the transmitting weight vector at symbol rate, thus resulting desired phases at the intended receiver and producing randomnesses at the undesired eavesdroppers. Different from the existing works that are only feasible for the case of single-path mmWave channels, our proposed algorithms are applicable to the more general multi-path channels.
Xuejing Zhang is currently working toward the Ph.D. degree in signal and information processing at the School of Information and Communication Engineering, University of Electronic Science and Technology of China (UESTC), Chengdu, China. Since November 2017, he has been a visiting student at the University of Delaware, Newark, DE, USA. His research interests include array signal processing and wireless communications.
