Performance analysis of DSSS- and CSS-based physical layer for IoT transmission over LEO satellites

Performance analysis of DSSS- and CSS-based physical layer for IoT transmission over LEO satellites

To determine a suitable waveform for Internet of Things (IoT) transmission over low-Earth orbit (LEO) satellites, this paper reports the results of a performance comparison between chirp spread spectrum (CSS)-based LoRa and direct sequence spread spectrum (DSSS)-based Ingenu. The performance of both...
