Abstract

The invention discloses a three-dimensional spectrum situation completion method based on a generative adversarial network, and the method comprises the steps: obtaining stored historical or experience radio monitoring data offline, and obtaining a plurality of complete three-dimensional spectrum situations or field intensity training data; performing iteration and adversarial offline training on the generative adversarial network variation to obtain the generative adversarial network variation of which the three-dimensional spectrum situation or the field intensity completion mechanism is learned; acquiring actual radio monitoring data of the current three-dimensional target area on line, and preprocessing to obtain defect spectrum situation or field intensity measured data of the three-dimensional target area; inputting the obtained measured data into the generative adversarial network variation to obtain output data of the generative adversarial network variation, and processing to obtain the current three-dimensional target area completion spectrum situation or field intensity. The method is applied to the three-dimensional spectrum situation or the field intensity in the space-air-ground information network, and the complementation error of the three-dimensional spectrum situation or the field intensity can be effectively reduced.

Description

technical field [0001] The present invention relates to the technical field of communication technology, in particular to a three-dimensional spectrum situation or field strength complement method and device based on a generative countermeasure network. Background technique [0002] In recent years, with the continuous development of the integration of space, space and ground information networks in our country, satellite networks and ground mobile networks have existed as normal basic networks, and various relay networks based on drones or other aerial platforms will form the link between the sky and the ground. The communication system is ushering in a major evolution of the 6G form from terrestrial 5G to aviation 6G. However, following this, the number of wireless intelligent terminals and services in the space-space-ground information network has increased rapidly, and the sharp contradiction between the increasingly scarce spectrum resources and the underutilization of ...
