The application relates to a signal modulation method, a demodulation method and a LoRa communication system. A total bit stream is divided into a plurality of parts, and is mapped into a frequency index set through G frequency index values. G LoRa signals are generated according to corresponding spreading factors, and are superimposed to obtain a single multiplexing signal of the spreading factor.
