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 proliferation effect of multipath effect has been the main problem of wireless channel research. The author uses a self-developed wireless channel simulation software to simulate the main channel characteristics in a micro-area environment. The description of the main channel characteristics such as propagation loss, delay spread and angle spread in a typical micro-environment is obtained.
