摘要
多径效应产生的扩散效应一直是无线信道研究的主要问题。作者利用自行开发的无线信道仿真软件对微区环境下的主要信道特性进行了大量的仿真。得到了典型微区环境下的传播损耗、时延扩展和角度扩散等主要信道特性的描述。
The dispersive characteristics of the wireless channel is a major problem in wireless communication. The authors has developed a wireless channel simulator and used it to predict the channel characteristics of the specific micro-cell. The characteristics include delay spread, angular spread and path loss. After the study of simulation, the author got some descriptions of the major characteristics of the wireless channel in micro-cell environment.
