چکیده
This paper proposes the design of a global-scale free-space optics/quantum key distribution (FSO/QKD) network based on geosynchronous (GEO) satellite as secret source and low-Earth orbit (LEO) satellites relay nodes for multiple legitimate users ground. The continuous variable QKD (CV-QKD) protocol with dual-threshold/direct detection (DT/DD) receivers is employed. system performance analyzed by considering spreading loss, atmospheric attenuation, turbulence. Based criteria proposed system, we investigate feasibility case study Japan unauthorized receiver attack (URA) beam-splitting (BSA). In addition, analyze secret-key rate perform Monte Carlo simulations to verify analytical results.

Design of Observer-based H∞ Controller for Robust Stabilization of Networked Systems Using Switched Lyapunov Functions
In this paper, H∞ controller is synthesized for networked systems subject to random transmission delays with known upper bound and different occurrence probabilities in the both of feedback (sensor to controller) and forward (controller to actuator) channels. A remote observer is employed to improve the performance of the system by computing non-delayed estimates of the sates. The closed-loop s...
متن کاملDesign of a novel congestion-aware communication mechanism for wireless NoC architecture in multicore systems
Hybrid Wireless Network-on-Chip (WNoC) architecture is emerged as a scalable communication structure to mitigate the deficits of traditional NOC architecture for the future Multi-core systems. The hybrid WNoC architecture provides energy efficient, high data rate and flexible communications for NoC architectures. In these architectures, each wireless router is shared by a set of processing core...
متن کاملDesign aspects of satellite-cellular hybrid wireless systems
In this paper, we investigate various issues related to the design of satellite-cellular hybrid systems. First, we review the fundamental problems of channel partitioning and call admission/assignment. Second, we study the impact of di erent frequency reuse constraints, in both layers, on the optimum channel partitioning. Third, we investigate, analytically and via simulation, the e ect of redu...
متن کاملDocument Delivery Design: Systems for Users, Not Users for Systems
Based around the Feasibility Study into a National Union Catalogue for the UK (UKNUC) and input into the investigation of the future of union catalogues in Denmark, this paper suggests some of the ‘background’ issues that need consideration in the design of document delivery systems. It is not intended to address the full range of issues in modern document delivery systems and does not, for exa...
