On the Advantage of Coherent LoRa Detection in the Presence of Interference
Orion Afisiadis, Sitian Li, Andreas Burg +1
It has been shown that the coherent detection of LoRa signals only provides marginal gains of around 0.7 dB on the additive white Gaussian noise (AWGN) channel. However, ALOHA-base…
