Abstract

The invention discloses a differential game-based satellite-ground communication uplink resource allocation method, which comprises the following steps of: setting a priority in satellite-ground communication, and dividing services participating in service resource allocation into a high-priority group and a low-priority group according to the priority, service resources are distributed to the businesses in the different groups through the central controller subsequently; constructing a utility function of a business service request, and maximizing the utility of service resource allocation by defining service resource allocation utility and influence cost in satellite-ground communication as a target optimization function; constructing a dynamic change state of service resources in satellite-ground communication; and introducing a differential game theory, solving a Nash equilibrium solution, and obtaining the optimal service resource allocation of each service. According to the method provided by the invention, the optimal service resource allocation of services in different priority groups can be calculated and solved, so that efficient response of service requests in satellite-ground communication is realized.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a resource allocation method for satellite-ground communication uplink based on differential game. Background technique [0002] In the satellite-to-ground communication system, the satellite ground station implements service requests through the uplink. With the development of Internet technology and 5G technology, data traffic and service requests have increased significantly, and ground spectrum resources and spectrum resources used by satellites are in a state of scarcity. , the prior art cannot realize efficient allocation of service resources in the uplink. Contents of the invention [0003] In view of the above problems, the purpose of the present invention is to provide a resource allocation method for satellite-to-earth communication uplink based on differential game. In order to maximize the utility of service resource allocation, the concept of priori...
