RIS Improves LoRa Interference Resistance

This paper proposes using reconfigurable intelligent surfaces (RIS) to improve the interference resistance of long-range (LoRa) communication systems. The RIS intelligently controls the wireless propagation environment to enhance the desired signal and suppress interference from other LoRa devices. Analytical and simulation results confirm the proposed RIS-aided system achieves better bit error rate performance than conventional LoRa under interference.
