中文说明：IEEE 802.11 a 信道模型针对室内无线局域网带宽达 100 MHz、 2 和 5 千兆赫的频率。信道模型包括一组 6 轮廓，标记为 A 到 F，涵盖方案平坦衰落，住宅、 住宅/小型办公室、 典型的办公室、 大型办公和大空间 （室内和室外）。每个信道模型具有包括阴影的路径损耗模型和 MIMO 多径衰落模型，介绍了多径延迟分布、 空间属性、 K 系数分布和多普勒频谱。
English Description：
The IEEE 802.11a channel models are designed for indoor wireless local area networks for bandwidths of up to 100 MHz, at frequencies of 2 and 5 GHz. The channel models comprise a set of 6 profiles, labeled A to F, which cover the scenarios of flat fading, residential, residential/small office, typical office, large office, and large space (indoors and outdoors). Each channel model has a path loss model including shadowing, and a MIMO multipath fading model, which describes the multipath delay profile, the spatial properties, the K-factor distribution, and the Doppler spectrum.
