application example 1

[0122] Suppose there are K low-orbit satellite nodes in the low-orbit satellite communication system, and K satisfies K≡{1,2,...,K}. Any satellite node i realizes the effective transmission of information between satellite nodes by controlling its transmission power and information transmission rate. For low-orbit satellite communication systems, the communication channel between satellite nodes can be regarded as an interference channel, and the channel interference coefficient between the information source node and the destination node can be obtained through the loss of the transmission path. Assume that the Gaussian distribution is satisfied during the transmission of information, and the Gaussian noise variance can be expressed by σ 2 to represent, then in this low-orbit satellite communication system, the signal-to-noise ratio of information transmission of any satellite node i can be expressed as formula (1),

Abstract

The invention relates to a satellite resource control method and apparatus for solving the problem of low utilization rate of onboard resources of a conventional satellite. The method comprises the following steps: calculating a unit utility value and a power control value of a satellite according to a transmission parameter of the satellite; calculating a utility rate control value of the satellite according to the unit utility value; constructing an optimization objective function of the satellite according to the utility rate control value, the power control value and an estimation factor;and obtaining the optimal transmission power and an optimal transmission rate of the satellite according to the optimization objective function. By adoption of the satellite resource control method and apparatus provided by the invention, the efficient information transmission between satellite nodes can be achieved under the condition of limited resource constraints.

Description

technical field [0001] The present disclosure relates to the field of satellite communication, in particular to a satellite resource control method and device. Background technique [0002] In low-orbit satellite communication systems, due to technical and cost constraints, the on-board load capacity is much lower than that of ground equipment and networks under the same circumstances. Therefore, for low-orbit satellite communication systems, a key issue is how to dynamically control antenna transmission power and information transmission rate, realize reasonable satellite resource allocation, and improve the effectiveness of resource utilization on low-orbit satellites. Contents of the invention [0003] In view of this, the present disclosure proposes a satellite resource control method and device to solve the problem of low utilization of resources on traditional satellites. The method includes: [0004] Calculate the unit utility value and power control value of the s...
