This invention discloses a multipath-resistant LoRa communication method combining block interleaving and matched filtering, belonging to the field of Internet of Things (IoT) technology. The steps are as follows: Block interleaving reduces the amplitude of strong multipath signals by dividing the signal into equal blocks and then swapping the order of these blocks, followed by deinterleaving at the receiver; matched filtering increases the signal-to-noise ratio (SNR). Matched filtering is selected based on amplitude criteria, first filtering the preamble symbol, then performing circular correlation operations using the preamble and data symbols. This method effectively resists multipath interference and improves the bit error rate performance of LoRa communication. It is low in complexity, low in power consumption, and simple to implement, making it suitable for multipath-intensive indoor and outdoor communication scenarios and shallow water acoustic communication.
