摘要：

In recent years, LoRa has become one of the most popular solutions for Internet of Things (IoT) services owing to its low-cost and low-energy characteristics. Although with growing interest in the literature, little attention has been paid for LoRa on the preamble detection. In this letter, we give a detailed analysis on the preamble detection under the low-complexity transceiver implementation when with initial timing and frequency offsets. The effects of the offsets on preamble detection performance are analyzed and some unrevealed issues are addressed, leading to a robust design of the preamble.
