Abstract

The paper deals with the features of signal processing in receiving devices using LoRa technology. A feature of the technology is the ability to build a radio network for transmitting messages over long distances under the condition of long-term battery operation. The main attention is paid to the study of the influence multipath propagation on the operation of the receiving device. For this purpose, the basic characteristics of the received signal, its frequency properties, the possibilities of spreading the spectrum, encoding and recovering the transmitted information, receiving a packet of individual pulse signals and the quality of packet processing as a whole, as well as the effect of multipath propagation, are studied. The technique for studying a receiver in a confined space with an estimate of the calculated and experimental data is proposed. The studies were carried out according to the "point-to-point" schemes. The test results are given.

基于LoRa技术的信号处理特点

本文论述了采用LoRa技术的接收设备信号处理的特点。该技术的一个特点是，在电池长期使用的情况下，能够建立一个远距离传输信息的无线网络。重点研究了多径传播对接收设备运行的影响。为此，研究了接收信号的基本特性、频率特性、扩展频谱的可能性、编码和恢复传输信息的可能性、接收单个脉冲信号的分组以及整个分组处理的质量，以及多径传播的影响。提出了一种利用计算数据和实验数据对密闭空间中的接收机进行研究的方法。这些研究是根据“点对点”方案进行的。给出了试验结果。
