摘要：

In this paper, we investigate the performance of space-time block-coded multiple-input-multiple-output (STBC-MIMO) LoRa system over Nakagami-m and Ricean fading channels with perfect and imperfect channel state information (CSI). Specifically, we derive the closed-form bit-error-rate expressions and analyze the diversity order of the STBC-MIMO LoRa system with perfect and imperfect CSI, where two common channel estimation error models are considered. Moreover, we perform simulations to evaluate the coverage performance of the system and to verify the accuracy of the theoretical analyses.
