| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | While Long Range Wide Area Network (LoRaWAN) has gathered remarkable attention, it experiences frequent LoRa signal collisions that lead to severe degradation of network capacity. Thus, this letter proposes a novel technique named LiCo to resolve LoRa signal collisions. Unlike existing approaches incurring considerable computational overhead, LiCo aims at a more lightweight way. Specifically, LiCo performs one-shot demodulation regarding all colliding signals and simply compares the demodulation results without any complicated arithmetic. Theoretical and experimental results show that LiCo can significantly reduce the computational overhead while achieving similar collision resolution performance as the state of the art. | |
