本文研究人员存在对900 MHz室内窄带无线信道的影响，发现人员增多导致信道变化加剧，并通过概率分布参数和二阶统计量进行表征与验证。
AI 中文摘要
低于1 GHz的无线通信适用于物联网（IoT）应用，因为它具有更大的覆盖能力且功耗更低。考虑到环境中的人员和物体可能导致信道变化，本文旨在评估人员存在对900 MHz室内窄带无线信道的影响，并表征小尺度现象。随着人员数量的增加，通信信道的变化更加显著，这反映在用于表征信号随机部分的概率分布参数上。此外，使用二阶统计量分析数据，并应用拟合优度检验以确认信号相对于分布的行为。
英文摘要
Wireless communication under 1 GHz is suitable for Internet of Things (IoT) applications due to larger coverage capability with less power consumption. Bearing in mind that people and elements contained in the environment can cause variations in the channel, this paper aims to evaluate the effect of the presence of people on a 900-MHz indoor narrowband wireless channel, as we characterize the small-scale phenomena. With the increase in the number of people, a greater variation in the communication channel was noticed, which is reflected in the parameters of the probability distributions used in the characterization of the random part of the signal. In addition, second-order statistics were used to analyze the data and an adherence test was applied to confirm the behavior of the signal in relation to the distributions.
