无线传播信道一直是无线通信系统中的重要研究部分。目前,随着4G等技术的商用,不同的应用频率.接入技术和信道带宽都将带来无线传播信道的巨大变化。本文对室内环境进行分析,总结出了两种室内场景的部署及其使用环境。通过对室内信道中的干扰,信道噪声,室内信道与室外信道差异以及信道特性对信号传输的影响进行研究与分析,总结出了多种室内信道模型。
Wireless propagation channels have long been an important part of research in wireless communication systems. At present, with the commercialization of technologies such as 4G, different application frequencies, access technologies and channel bandwidths will bring about tremendous changes in the radio propagation channel. This article analyzes the indoor environment, summed up the deployment of two indoor scenarios and their use of the environment. By analyzing and analyzing the influence of indoor channel interference, channel noise, indoor channel and outdoor channel and channel characteristics on signal transmission, a variety of indoor channel models are summarized.
