    Interconnection and coexistence of heterogeneous network:requirements, challenges, and architecture by Hongbin LUO, Shan ZHANG, Zhiyuan WANG

    Published 2022-06-01
    “…With the rapid development of the network technology and applications, many networks with different types of topologies and services have been emerging, such as Internet, satellite Internet, industrial Internet, unmanned aerial vehicle swarm network, and vehicle Internet, forming a situation in which many differentiated network systems coexist, to this end, the requirements and challenges were elaborated for heterogeneous networks to be integrated and coexist.Then CoLoR, an architecture for securely and efficiently interconnect heterogeneous networks was introduced.Based on the consistent function (i.e., information transmission) among heterogeneous network systems, CoLoR introduces multi-dimensional namespace for the universal representation.Moreover, CoLoR decouples the intra-domain routing and the inter-domain routing to ensure the evolution ability.Finally, CoLoR also constructs an efficient cross-domain communication mode and a security guarantee mechanism.…”

    Modulation recognition method based on multi-inputs convolution neural network by Xiong ZHA, Hua PENG, Xin QIN, Guang LI, Tianyun LI

    Published 2019-11-01
    “…In order to identify the main modulation modes adopted in current satellite communication systems,a signal modulation recognition algorithm based on multi-inputs convolution neural network was proposed.With the prior information of the signals and knowledge of the network topological structure,the time-domain signal waveforms were converted into eye diagrams and vector diagrams to represent the shallow features of the signals.Meanwhile,the modulation recognition model based on multi-inputs convolution neural network was designed.Through the training of the network,the shallow features were deeply extracted and mapped.Finally,the signal modulation recognition task was completed.The simulation results show that compared with the traditional algorithms and deep learning algorithms,the proposed method has a better anti-noise performance,and the overall recognition rate of this algorithm can reach 95% when the signal-to-noise ratio is 5 dB.…”
