WebbThis article presents an independently developed packet reception algorithm, which drastically improves the physical performance of LoRa communication links. The advanced signal presence detection, synchronization, and symbol detection strategies are shown to significantly increase packet reception ratios in extremely adverse noise conditions. WebbSNR(Signal-to-noise ratio) is a standard measure of the amount of background noise present in a speech (or other) signal. It is defined as the ratio of signal intensity to noise intensity, expressed in decibels, e.g. SNR_dB = 20.log10(S_rms / N_rms) where S_rms is the root-mean square of the speech signal (without any
