Analytical and Experimental study for LoRa Modulation
Résumé
In this paper, the performance of Long Range
(LoRa) Internet of Things (IoT) technology is investigated. By
considering Chirp Spread Spectrum (CSS) technique of LoRa,
an approximation of the Bit Error Rate (BER) is presented and
evaluated through intensive simulations. Unlike previous works
which present the BER of LoRa in terms of the ratio of energy
ber bit to noise ratio only without any proofing, our presented
work expresses BER in terms of LoRa’s modulation patterns such
as the spreading factor, the code rate, the symbol frequency and
the SNR. Numerical results are carried out in order to investigate
the LoRa performance and to illustrate the accuracy of the new
BER expression.
