Abstract

This letter proposes a novel technique named LiCo to resolve LoRa signal collisions. Unlike existing approaches that introduce considerable computational overhead due to redundant LoRa demodulation operations, LiCo aims at a more lightweight way by simply performing one-shot demodulation regarding all colliding signals. For the separation of colliding signals, LiCo further analyzes the demodulation results in a comparative manner with no need to apply any complicated arithmetic. Theoretical and experimental results show that LiCo can reduce the computational overhead while achieving similar collision resolution performance as the state of the art.
