A novel orthogonal LoRa multiple access algorithm for satellite Internet of Things

In recent years, LoRa has been extensively researched in the satellite Internet of Things (IoT). However, the multiple access technology of LoRa is still one of the bottlenecks of satellite IoT. To improve the multiple access performance of LoRa satellite IoT, based on the orthogonality of LoRa symbols in the fractional domain, this paper proposes a low complexity Orthogonal LoRa Multiple Access (...
