More Information
Summary:The channel measurement and modeling of fading characteristics of 25.5 and 39.5 GHz bands in corridor environment are investigated. An automatic measurement system owning a sufficient dynamic range is designed to overcome the prominent attenuation in the millimeter-wave band. After conducting extensive measurements, large-scale and small-scale fading characteristics are obtained and compared. Good-of-fit test is applied to validate whether the assumed log-normal distribution can describe the shadow fading characteristics. The closed-in log-distance path loss model and the least-square fitted model are respectively employed to analyze the effects of frequency and antenna polarization on large-scale fading. Besides, typical small-scale fading parameters such as root-mean square (RMS) delay spread and in-cluster RMS angle spread are extracted utilizing the bisecting k-means clustering algorithm.
