摘要
Abstract
In order to improve the success probability of random access of high-throughput satellites,a random access control technology for the high-throughput satellite communication system is proposed.High-throughput satellites have overlapping coverage areas between multiple beams,and the user access in overlapping coverage areas can be controlled to optimize the load of each beam and improve the system throughput rate.By deducing and analyzing the packet error probability of the successive interference cancellation algorithm,the maximum system load under different packet error probability requirements is obtained.Based on this load value,an adaptive access control strategy is designed.When the system load does not exceed the maximum load,the beam load can be balanced by the access control strategy,and when the system load exceeds the maximum load,the system load can be controlled by restricting user access probability.关键词
