The invention provides a LoRa system and a LoRa physical layer enhancement method based on intelligent reflective surface beamforming and index modulation, in the system, a transmitting side at least comprises Nk LoRa nodes equipped with single transmitting antennas and an RIS with N passive reflective elements, the RIS is used for improving a wireless propagation environment, beamforming is realized by controlling the phase of each passive reflective element, and the LoRa physical layer enhancement method is used for enhancing the physical layer of the LoRa. The instantaneous signal-to-noise ratio under the antenna combination is activated to the maximum, and the bit error rate performance is improved; a receiver at least comprises a LoRa gateway equipped with NR receiving antennas, multiple receiving antennas at the LoRa gateway are used for index modulation, and Nk receiving antennas in the NR receiving antennas are activated in each symbol period and serve as information transmission entities to bear additional information, so that the transmission throughput is remarkably improved. According to the LoRa physical layer enhancement method applied to the LoRa system, the wireless propagation environment is controlled through RIS beam forming to improve the quality of received signals, and the spectrum efficiency is improved by ingeniously utilizing the IM principle of multiple receiving antenna indexes, so that the LoRa physical layer enhancement method has high transmission rate and high reliability.
