Title: A Connected Sky: 6G Communications for UAVs

Abstract:

The integration of UAVs into unify international air space requires the use of advanced communications with high-mobility communication platforms to provide line-of-sight links and further assist the terrestrial communications. 6G aims to provide ubiquitous wireless connectivity for the whole world. However, the demands for high-quality and ubiquitous wireless services impose enormous challenges to existing cellular networks. Unmanned aerial vehicles (UAVs), due to their agile maneuverability, can be dispatched as high-mobility aerial communication platforms to provide high quality links and further assist the terrestrial communications in 6G.Hence, integrating UAVs into 6G networks is a promising solution to achieve such goals. 6G calls for a paradigm on the design of both cellular and UAV communications systems due to the high altitude and mobility of UAVs, the unique channel characteristics of UAV-ground links; the asymmetric quality of downlink and uplink data transmission; weight and power limitations of UAVs; as well as the intra-system and inter-system interference of the integrated networks. In order to provide users with smooth service experience and improve the resource utilization of integrated UAVs and 6G networks

Title: Efficient DOA Estimation Method for Reconfigurable Intelligent Surfaces Aided UAV Swarm

Abstract:

The conventional direction of arrival (DOA) estimation methods are performed with multiple receiving channels. A changeling DOA estimation problem is addressed in a different scenario with only one full-functional receiving channel. A new unmanned aerial vehicle (UAV) swarm system using multiple lifted reconfigurable intelligent surface (RIS) is proposed for the DOA estimation. The UAV movement degrades the DOA estimation performance significantly, and the existing atomic norm minimization (ANM) methods cannot be used in the scenario with array perturbation. Specifically, considering the position perturbation of UAVs, a new atomic norm-based DOA estimation method is proposed, where an atomic norm is defined with the parameter of the position perturbation. Then, a customized semi-definite programming (SDP) method is derived to solve the atomic norm-based method, where different from the traditional SDP method, an additional transforming matrix is formulated. Moreover, a gradient descent method is applied to refine the estimated DOA and the position perturbation further. Simulation results show that the proposed method achieves much better DOA estimation performance in the RIS-aided UAV swarm system with only one receiving channel than various benchmark schemes.

Title: Physical layer authentication method for the Internet of Things based on radio frequency signal gene characteristics

Abstract:

Data attacks from illegal access devices of the Internet of Things will cause serious interference and threats to the entire network. It is difficult to ensure the security of the communication system only by relying on traditional application layer password authentication methods. Therefore, it is of great significance to design an effective physical layer authentication system. To effectively identify IoT objects, and prevent the occurrence of problems such as device cloning, replay attacks and user identity impersonation, this report proposes a novel physical layer authentication method for Internet of Things based on radio frequency signal gene characteristics. First, properties and types of radio frequency fingerprint identification technology are described. Second, the shortcomings of existing fingerprint recognition technology based on traditional machine learning are described with involvement of detailed experimental tests. Next, given the limitations of existing methods, extensive literature review from radio frequency fingerprint to radio frequency gene cognition has been made. The concept of gene characteristics of the radio frequency signal is proposed, which is inspired by the biological gene, since the radio frequency signal has materiality, informationality, transitivity, vulnerability and dividability, and these characters are similar to the biological gene. At last, the radio frequency signal gene feature extraction and recognition are explored through simulation analysis and experimental analysis.
