Embodiment Construction
[0038] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0039]The method for allocating resources of a multi-beam satellite communication system according to the present invention considers that there are multiple users and multiple controllers in the multi-beam satellite system, and users can choose a direct transmission mode or a relay transmission mode. In the two different transmission modes, the user-satellite beam and the controller-satellite beam both adopt the frequency division multiple access method, and the data transmission has no interference; while the data transmission between multiple user-controller pairs can adopt the frequency sharing method. Optimize the design of user-controller-satellite beam association and power resource allocation strategy to maximize users and speed and improve overall system performance.

The invention relates to a multi-beam satellite communication system resource allocation method, which belongs to the technical field of wireless communication. The method comprises the following steps: S1, modeling of controller-satellite beam selection variables is carried out; S2, modeling of user-controller and user-satellite beam correlation variables is carried out; S3, modeling of a multi-beam satellite system and a rate is carried out; S4, modeling of user-controller-satellite beam correlation restriction conditions and resource allocation restriction conditions is carried out; and S5,based on maximization of the user and the rate, a user correlation and resource allocation policy is determined. Through carrying out joint user correlation and power allocation on the multi-beam satellite communication system, maximization of the user and the rate can be realized.
Description
technical field [0001] The invention belongs to the technical field of wireless communication, relates to the technical field of satellite communication, in particular to a resource allocation method of a multi-beam satellite communication system. Background technique [0002] In recent years, satellite communication technology has become an effective way to provide user information access. However, the limited spectrum resources in the satellite communication system and the rapidly developing user service requirements have formed a prominent contradiction. How to use efficient user association and resource allocation technologies to enhance the performance of the satellite communication system has become an important research topic. [0003] At present, there have been studies considering the allocation of multi-beam satellite communication resources, such as the patent (application number 201711007962.X) "Ka multi-beam satellite communication resource allocation method bas...
