| Abstract |
LoRa (long range) is one of the wireless communication techniques capable of low-power and long-distance communications, and is expanding its application scope in the IoT (internet of things) communication field. Recently, many efforts have been made to use LoRa to communicate with high-speed unmanned aerial vehicles (UAVs) or low earth orbit (LEO) satellites. In this paper, we propose a LoRa symbol detection scheme where symbol duration is divided into two coherent correlation intervals to obtain a robust detection performance against Doppler shift in high-speed moving environments, and verify its performance through computer simulations. |
