Abstract

This letter looks at the effects of mobility and diversity. The transmitter is mobile in this scenario, while the receivers are diverse. The mobile transmitter will induce a doppler effect on the signal being sent. The receiver antennae will be able to estimate the doppler effects and remove them. It will then leverage the multiple antennae to improve the reception of the signal. Doing both improves the packet detection rate in a low signal to noise ratio (SNR) scenario. When multiple mobile transmitters are used, the packet detection rate in a low SNR environment was poor.

卫星LoRa多普勒效应分析

这封信着眼于流动性和多样性的影响。在这种情况下，发射器是移动的，而接收器是多种多样的。移动发射机将对所发送的信号产生多普勒效应。接收天线将能够估计多普勒效应并消除它们。然后，它将利用多个天线来改善信号的接收。在低信噪比（SNR）的情况下，两者都可以提高数据包检测率。当使用多个移动发射机时，低信噪比环境下的数据包检测率较差。
