This paper deals with the bit error rate (BER) of LoRa signal over Rayleigh and Rice channels. Exact analytical expressions of the BER in LoRa systems have been proposed in the literature, but they are not tractable and raise problems of computation precision. We then hereby suggest asymptotic expressions of the BER, which are at the same time
tractable and accurate over a wide BER range.
