摘要

给出了2.4 ghz无线信道的室内测量实验结果。这些测量包括在一些室内环境中的准静态和时变信道条件。评估了四个感兴趣的信道传播特性。在时变环境下,测量了无线信道的多普勒扩频。在准静态环境下,确定了信道的平均超额延迟、平均延迟扩展和相干带宽。讨论了这些传播特性对多天线无线系统的影响及其在室内使用的适用性。

Experimental studies of the 2.4-GHz ISM wireless indoor channel
Experimental results from indoor measurements of the 2.4-GHz wireless channel are presented. These measurements include both quasi-static and time-varying channel conditions in a number of indoor environments. Four channel propagation characteristics of interest are evaluated. For the time-varying environment, the Doppler spread of the wireless channel is measured. For the quasi-static environment, mean excess delay, rms delay spread, and coherence bandwidth of the channel are determined. The effect each of these propagation characteristics has on multiple antenna wireless systems and their suitability for indoor use is discussed.
