走廊环境极化信道大尺度特性测量与建模

Measurement and modeling of large scale channel fading under corridor scenario

为了建立室内走廊环境2.4-2.5GHz极化大尺度衰落模型,采用矢量网络分析仪搭建无线信道测量平台,并利用该平台在典型教学楼走廊环境下测量信道。通过测量数据提取信道的损耗系数、交叉极化隔离、阴影衰落方差、频率补偿系数等大尺度特性参数,建立该环境极化信道的大尺度衰落模型。测量结果表明,在2.4-2.5GHz频带,频率对大尺度衰落的影响可忽略不计。

In order to establish corridor polarized large scale channel model,channel measurement is carried out under a typical corridor environment by using a vector network analyzer.Based on the measured data,large scale parameters such as path loss,cross-polarization discrimination,variance of shadow fading and frequency compensation are measured.A corridor polarization large scale channel model is established.The measurement result shows that the frequency compensation is neglectable in 2.4-2.5GHz frequency band.
