摘要
本文针对微功率无线通信信道建模这一核心问题,通过分析无线信号传播模型,介绍了大尺度衰落模型和小尺度衰落模型两种传播模型。并对依托于这两种模型下的对数距离路径损耗模型、Longley-Ric、Okunura-Hata模型及Suzuki信道模型等经验模型进行了分类详细概述,总结了每种模型的优缺点以及适应范围。文章最后对信道建模方面的研究做了总结和期望。指出Suzuki市区模型适合电网用户环境下的微功率无线通讯。
This paper focuses on the core problem of micro-power wireless communication channel modeling. By analyzing the wireless signal propagation model, We introduce the two models of large-scale fading model and small-scale fading model and discusses empirical model for logarithmic distance path loss model, Longley-Ric, Okunura-Hata model and Suzuki channel model under these two models. The advantages and disadvantages of each model and the scope of adaptation are summarized. In the end, the article concludes and expects research on channel modeling. It is pointed out that the Suzuki urban model is suitable for micro-power wireless communication in the State Grid user environment.
