N2 - This paper addresses the energy consumption concern of LPWAN by proposing an extension for the LoRa modulation. Conventional LoRa encodes data in the frequency shift of a chirp, our extension consists in encoding additional data in the phase- shift using the PSK modulation, giving rise to the PSK-LoRa. Our motivation is to encode more data per unit of time without performance degradation, such that we have a more energy efficient system. In order to assess the performance of PSK-LoRa, we derive approximate bit error rate and packet error rate expressions, and then we compare against simulation. For instance, both analytical and numerical outcomes demonstrate that QPSK-LoRa has no performance loss in comparison to LoRa, indicating the feasibility of the new scheme.
