MIMO-LoRa for High-Data-Rate IoT: Concept and Precoding Design

초록

Long range (LoRa) is a widely adopted modulation scheme for Internet of Things (IoT), but its data rate is low. To tackle this problem, in this letter, we introduce a novel concept of MIMO-LoRa: an integration of multiple-input multiple-output (MIMO) and LoRa for achieving high data rates. We also design a precoding for the proposed MIMO-LoRa system to further enhance the link reliability. The validity and effectiveness of the proposed MIMO-LoRa system are demonstrated through numerical simulations.
