On the LoRa Modulation for IoT: Waveform Properties and Spectral Analysis [PDF]
IEEE Internet of Things Journal, 2019 An important modulation technique for Internet of Things (IoT) is the one proposed by the low power long range (LoRa) alliance. In this paper, we analyze the $M$ -ary LoRa modulation in the time and frequency domains.
