Abstract

The invention discloses a cross-platform fusion communication method in a satellite-ground integrated frequency-hopping satellite system, which belongs to the technical field of satellite communication. This method is aimed at the comprehensive application of different types of platforms such as vehicles, ships, helicopters, and unmanned aerial vehicles in the satellite-ground integrated frequency-hopping satellite communication system. The design of time slot division and allocation, uplink and downlink transmission parameters variable by time slot, etc., adapts to the special requirements of different types of platforms, and realizes the cross-platform converged communication based on the unified carrier and signal frame in the uplink and downlink. The invention can reduce the complexity and cost of equipment realization while meeting the comprehensive application requirements of multiple types of platforms, and at the same time improve the utilization rate of system resources and the flexibility of platform applications.

Description

technical field [0001] The invention relates to a cross-platform fusion communication method in a satellite-ground integrated frequency-hopping satellite system, belonging to the technical field of satellite communication. Background technique [0002] With the expansion of application requirements and the development and construction of satellite communication systems, the application of satellite communication in the civilian field has become increasingly widespread, gradually expanding from ground fixed applications to vehicles, ships, aircraft and other types of platform applications. Therefore, the design of the satellite communication system is required to fully consider the particularities of different platforms such as vehicles, ships, helicopters, and drones, so as to meet the needs of satellite communication for multiple platforms. [0003] At present, the application of different types of platforms in satellite communication mainly uses different frequency bands o...
