Multi-beam low-orbit satellite intelligent dynamic channel resource allocation method

Abstract

The invention relates to the technical field of space-air-ground-sea integrated communication, in particular to a multi-beam low-orbit satellite intelligent dynamic channel resource allocation method.The method comprises: using a low-orbit satellite as an Agent; mapping the number of beam service request users at the current service request moment and the initial state of channel occupation by beams into an environment; at each service request moment, sending a service request, according to the environment where the low-orbit satellite is located, using a Q-learning algorithm to observe an environment state and acquire an award signal of the environment; learning a state-action value function, changing the channel resource allocation strategy step by step, to complete dynamic channel resource allocation of the low-orbit satellite mobile communication system. It can be avoided that the same channel resource is allocated to users or beams within the multiplexing distance, and a channelresource allocation scheme capable of enabling the overall performance of the low-orbit satellite mobile communication system to be optimal is achieved.

Problems solved by technology

However, each beam user can use all channel resources. During the resource allocation process, the same channel may be allocated to users who are closer to each other, which will cause interference and affect the quality of system communication services.
