    Published 2018-07-01
    “…With the rapid development of the internet,the network bearer content is gradually transformed from a service based on connection-based information interaction to a service based on content sharing (video).The network transmits a large amount of redundant information,resulting in abnormal large-scale investment.And the quality of the service is difficult to guarantee,and it is urgent to study and construct a network that matches the business development.The content sharing connection relationship and the communication network architecture connection relationship were studied,and the two-dimensional poor time distribution or three-dimensional distribution and other implementation methods were explored.CDN was constructed to construct the content edge node,and the core network,wireless network,bearer network architecture and network element deployment were optimized.And space-based network such as satellite was considered to introduce to build a scale-free small hop network on the existing communication network to achieve matching of network architecture and content distribution.…”

    Robust resource allocation algorithm for multicarrier NOMA security communication system by Yu ZHANG, Xiongwen ZHAO, Xiaoqing WANG, Suiyan GENG, Peng QIN, Zhenyu ZHOU

    Published 2022-03-01
    “…To improve the spectrum efficiency and enhance the information security of wireless network, a sum secrecy rate maximization-based robust resource allocation algorithm was proposed for a downlink multicarrier NOMA security communication system.Firstly, the artificial noise (AN) precoding vector was designed to be orthogonal to the legitimate channel, so that the legitimate transmission would not be affected by the AN.Then, considering the constraints of rate requirement of each user and the maximum transmit power of base station, a joint AN precoding, downlink data precoding and subcarrier allocation optimization problem was formulated under eavesdropping channel uncertainties.To solve that non-convex problem, it was decomposed into two joint optimization subproblems: precoding optimization and subcarrier allocation.The former was solved based on S-procedure and block coordinate descent (BCD) algorithm, the latter was solved by dynamic matching theory.Simulation results demonstrate that the proposed algorithm has good robustness and can effectively improve the sum secrecy rate.…”

    Published 2021-06-01
    “…With the fast growing demand for the wireless network intelligence, the future communication system will transform from the traditional data-oriented solution to a novel intelligence-of-everything (IoE)-based architecture.Semantic communication is a new communication technology which involves the meaning of message into the communication process.It is believed that semantic communication will have the potential to serve as the fundamental paradigm for the future IoE.The relationship between the semantic communication and IoE was discussed and the basic models and fundamental components of semantic communication were introduced.By discussing the limitations of point-to-point semantic communication, it was argued that the knowledge sharing and resource convergence-based semantic communication networking would be ideal for supporting the future massive scales of IoE systems.The basic components of the semantic communication networking system were discussed and a federated edge intelligence-based semantic communication networking architecture as a case study was considered.Simulation results show that semantic communication networking has the potential to further reduce the resource demand and improve the efficiency of semantic communication.Finally, open problems for future research were discussed.…”
