Abstract

The invention relates to a method for determining minisatellite joint transmission mode selection and resource allocation, and belongs to the technical field of satellite communication. The method comprises the following steps: S1, modeling a time slot identifier and a wireless channel model; S2, modeling a minisatellite request data packet transmission model; S3, modeling a minisatellite transmission mode association variable; S4, modeling a minisatellite energy collection model; S5, modeling a transmission mode selection limiting condition, an energy collection limiting condition and a resource allocation limiting condition; S6, modeling a cost function; and S7, determining a minisatellite joint transmission mode selection and resource allocation strategy based on cost function minimization. According to the invention, the network cost function optimization can be realized through the joint transmission mode selection and power distribution of the minisatellites.

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 small satellite joint transmission mode selection and resource allocation method. Background technique [0002] Small satellites have the advantages of low orbital height, low transmission delay with ground stations, miniaturization of user terminals and low power consumption, and efficient frequency multiplexing, etc., and have attracted widespread attention in recent years. However, the limited spaceborne resources in the small satellite network and the rapidly developing user service requirements have formed a prominent contradiction. How to use efficient data transmission and resource allocation technologies to enhance the transmission performance of the small satellite network has become an important research topic. [0003] In recent years, there have been studies considering the allocation of space...
