摘要

在卫星物联网蓬勃发展的过程中，随机接入协议因其信令开销较小、传输效率高、灵活性高、实现容易的特点被视为最适宜的通信协议，但由于负载变化剧烈，常规随机接入方式只在特定负载范围内具有优势，动态分配随机接入资源需要获取准确的时隙接入申请量。针对以上问题，提出一种随机接入自适应方案，可以根据未来负载量大小自适应选取恰当的随机接入方式，从而提高系统吞吐量，其中，负载量大小可以通过提出的负载量估计及预测方案得到。在传输环境存在窄带干扰时，引入扩频通信手段，使得随机接入自适应方案能够成功运行，并且提出的扩频随机接入自适应方案提升了系统吞吐量。

Abstract

In the process of the vigorous development of satellite internet of things

random access protocol is regarded as the most suitable communication protocol due to its characteristics of low signaling overhead

high transmission efficiency

high flexibility and easy implementation.However

due to drastic load changes

conventional random access mode only has advantages in the specific load range.Dynamic allocation of random access resources requires the accurate number of time slot access applications.In view of the above problems

a random access adaptive scheme was proposed

which could adaptively selected the appropriate random access mode according to the future load size

so as to improved the system throughput.The load size could be obtained through the proposed load estimation and prediction scheme.When narrowband interference exists in the transmission environment

the spread-spectrum communication means was introduced to made the adaptive scheme of random access run successfully.Moreover

the proposed adaptive scheme also improved the system throughput.
