摘　　要：从远距离无线电(Long Range Radio,LoRa)信号的基本原理出发,介绍了信号的调制与解调基本方法,重点分析了LoRa信号解调时所需参数的盲估计方法,综合其他研究成果提出了一种互相关峰值二维搜索的载波误差及信号同步检测方法,最后通过计算机仿真了高斯白噪声信道下LoRa信号的同步检测概率,验证了载波误差估计及同步检测方法的可行性。Based on the basic principle of Long Range Radio(LoRa)signal,this paper introduces the basic methods of signal modulation and demodulation,focuses on the blind estimation method of the parameters required for LoRa signal demodulation,and proposes a carrier error and signal synchronization detection method for two-dimensional search of cross-correlation peak values by synthesizing other research results.Finally,the synchronization detection probability of LoRa signal in the Gaussian white noise channel is simulated by computer,the feasibility of carrier error estimation and synchronization detection method is verified.
