High-throughput satellite frequency allocation method based on digital transparent processor

Abstract

The invention relates to a high-throughput satellite frequency allocation method based on a digital transparent processor. The method comprises the following steps: acquiring preposition information required by frequency allocation; according to the user priorities from high to low, selecting each user as a user to be distributed; determining a conflict object of the to-be-distributed user; moving out the frequency range of the conflict object from the total frequency [fmin, fmax], and taking the residual frequency as the available frequency of the user to be allocated; judging whether a frequency interval of which the continuous frequency is greater than or equal to the to-be-allocated user bandwidth exists in the available frequency or not; frequency intervals and sub-band numbers of all users are obtained, frequency allocation work of beams is completed, and the frequency interval and the sub-band number corresponding to each beam serve as final results and are sent to a satellite transponder system. The frequencies of different users in the same wave beam can be discontinuous, the bandwidth utilization rate of the system can be improved, the same-frequency interference of adjacent wave beams is reduced, and the carrier-to-interference ratio of the system is improved.

Description

technical field [0001] The invention relates to a method for allocating frequency of a high-throughput satellite based on a digital transparent processor, in particular to a method for adjusting beam subbands of a high-throughput satellite based on a digital transparent processor. Background technique [0002] The throughput of high-throughput satellites has reached one hundred gigabits per second. In the face of problems such as uneven geographical distribution of users and tidal effects of business hours, traditional high-throughput satellites with fixed resources have two prominent problems. First, some beams waste resources because they have no service requests; second, some beams have no resources and cause services to be rejected. With the application of flexible loads, especially digital transparent processors, it is very important to carry out dynamic adjustment of beam frequency resources. However, the frequency change will bring about the deterioration of the carr...

AI Technical Summary

Problems solved by technology

[0004] (1) The beam frequency of traditional communication satellites is continuous. Adjusting the bandwidth can easily introduce frequency interference. When calculating the bandwidth change of the beam, the adjacent beam interference caused by the bandwidth change is not considered;

[0005] (2) In the beam frequency allocation method, there is no frequency adjustment method based on a digital transparent processor
