Embodiment Construction

[0053] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0054] The present invention takes into account the deficiencies of existing research, and aims at the problem of on-board power resource allocation in a multi-beam satellite communication system, taking into account different types of users and specific service types, and constructing a The user terminal-oriented multi-beam satellite communication system downlink capacity model, and chooses to minimize the sum of second-order service rejections as the objective function, and models the power resource optimization problem as an optimization problem with constraints. Finally, Lagrangian dual theory and subgradient method are used to solve the problem.

[0055] to combine figure 1 and Figure 6 , the invention studies the problem of on-board power resource allocation in a multi-beam satellite communication system. The invention mainly solves the power resour...

Abstract

The invention discloses a power allocation algorithm in a multi-beam satellite communication system. The power allocation algorithm comprises the following steps: at first, creating a downlink capacity model of the multi-beam satellite communication system for a user terminal according to a power bandwidth balancing principle in the multi-beam satellite communication system; then, creating a constrained optimization problem model for the power allocation problem; and finally, solving through the Lagrangian duality theory and a subgradient algorithm. The power allocation algorithm provided by the invention has excellence on the aspects of total capacity of the system and the total refusal amount of two-order services, good system performance can be obtained, and valuable power resources can be effectively utilized.

Description

technical field [0001] The invention belongs to the technical field of resource allocation, and in particular relates to a power allocation algorithm in a multi-beam satellite communication system. Background technique [0002] In the multi-beam satellite communication system, the power resource on the star is limited. Due to the application of multi-beam antennas, it is possible to allocate power resources between different beams, and resource allocation technology has become an important research content in multi-beam satellite communication systems. By rationally allocating power resources between different beams according to business requirements and performance requirements, the overall performance of the system can be optimized, and better services can be provided for users. Therefore, it is of great practical value to rationally allocate limited power resources and effectively improve resource utilization. [0003] Power distribution technology in multi-beam satelli...
