Maritime Cross-Domain Collaboration Networking Communication Technology Based on Broadband Cognitive Stacked Networks

Abstract

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.
