Maritime Cross-Domain Collaboration Networking Communication Technology Based on Broadband Cognitive Stacked Networks
With the increasingly severe situation of enemy confrontation at sea,multi-platform deployment at the ocean is needed.Maritime wireless communication technology relying on single band including high frequency,very/ultra-high frequency,and microwave frequency can no longer meet the communication support needs of multi-link fusion networking,dynamic resource allocation,and systematic anti-interference for maritime cross-domain collaboration operations.A novel multi-link fusion network communication architecture based on broadband cognitive stacked networks was proposed.A comprehensive integrated radio frequency(RF)front-end was adopted for broadband RF resource management,and a data link fusion meta-model was formed by unifying bandwidth,time slot,and time and space.On this basis,a software communication system backend was adopted for multi-link fusion and stacked networking.Through technologies such as broadband spectrum sensing,cognitive spectrum access,and task-driven adaptive networking,dynamic adaptation to maritime multi-domain communication environments such as air,sea,and submarine was achieved,as well as cognitive decision-making in strong enemy confrontation environments.This could enhance the expansion,cross-domain transmission,and anti-interference communication capabilities of maritime communication networks.In-depth research on the key technologies of broadband cognitive stacked networks was conducted,and a feasible technical approach to broadband cognitive stacked networks was given,which could provide a reference for the system architecture design and technical research in this field.
