摘要

LoRa作为一种广域网技术，具有低功耗、广覆盖等特点，在物联网应用领域具有十分广阔的前景，近年来，已被部署在全球多个物联网中。低轨卫星网络广覆盖的优势使其成为实现海量物联网全球覆盖的必然技术。首先对LoRa技术的基本原理进行阐述；然后分析LoRa技术直接引入低轨卫星物联网后存在的问题；最后提出一套适合低轨卫星物联网的LoRa传输技术，重点解决低轨远距离低功耗传输条件下的LoRa帧同步问题和卫星高速移动导致的大多普勒频移对LoRa解调的不利影响。仿真结果表明，提出的联合同步及频偏估计算法能明显提高极低信噪比和大多普勒频移条件下LoRa技术的同步概率和传输可靠性。

Abstract

As an emerging wide area network technology

LoRa has the characteristics of low power consumption and wide coverage.It has very broad prospects in the field of internet of things applications.In recent years

it has been deployed in countless objects around the world.The advantages of wide coverage of low-orbit satellite networks make it an inevitable technology to achieve global coverage of massive internet of things.Firstly

the basic principles of LoRa technology were expounded.Then the problems existed after the LoRa technology was directly introduced into the low-orbit satellite IoT were analyzed.Finally

a set of LoRa transmission technology suitable for low-orbit satellite IoT was proposed

focused on solved the problem of LoRa frame synchronization under the condition of low-orbit long-distance low-power transmission

and the problem of LoRa demodulation caused by the high-speed movement of satellites due to the Doppler frequency off set.The simulation results showed that the proposed joint synchronization and frequency off set estimation algorithm could obviously improved the synchronization probability and transmission reliability of LoRa technology under the conditions of extremely low SNR and large Doppler frequency shift.
