Channel screening optimization method and system for communication terminal equipment

Abstract

The invention discloses a channel screening optimization method and system of communication terminal equipment, a plurality of satellites and a plurality of ground base stations are networked, when a new terminal accesses, channel screening is carried out on a new access terminal with resource competition occupation during data transmission, and the method comprises the following steps: acquiring wireless radio frequency channel signals of the plurality of ground base stations; performing virtual channel transmission matrix mapping on the virtual partitions of the ground base station based on respective data tasks of the original satellites to obtain an information source coding matrix and a channel coding matrix; on the basis, the condition that the modulus of the transmission capacity of the wireless radio frequency channel signal is smaller than the maximum receiving power of the virtual partition and the condition that the signal-to-noise ratio strength of the wireless radio frequency channel signal is minimum are taken as conditions; dynamic screening and channel preliminary screening of virtual partitions are realized; and according to the dynamic parameters, obtaining the priority of arrangement, and according to the priority, combining with other terminals to realize channel fine screening. The method is used for solving the problem of balance switching between a satellite and a ground station when resources are limited in the prior art and improving the effective utilization rate of satellite communication resources.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and system for channel selection and optimization of communication terminal equipment. Background technique [0002] The satellite communication system is mainly composed of three parts: the satellite terminal, the ground terminal and the user terminal. The satellite terminal plays the role of a relay station in the air, that is, the electromagnetic wave sent by the ground station is amplified and then sent back to another ground station. The ground station is the satellite system and The interface of the ground public network, the ground user terminal can also form a link through the ground station to enter and exit the satellite system. [0003] In practical applications, one satellite may communicate with multiple ground stations at the same time, and multiple satellites may also communicate with the same ground station at the same time. In the case of limited ...
