摘要

This study reports the results of an indoor propagation measurement campaign and channel characterisation at 11 and 14GHz, which are the candidate bands for the future communication systems. The measurement procedure allows the characterisation of both the large- and small-scale statistics of line-of-sight (LOS) and non-LOS (NLOS) channels. Based on the measurements, a log-distance path loss model is proposed, and the root-mean-square (RMS) delay spread is discussed. A Nakagami distribution is found to well describe the statistics of the small-scale fading, by using Kolmogorov-Smirnov, Chi-square, and Anderson-Darling tests. A distance dependent linear model is proposed to predict the Nakagami m-parameter. In addition, the cross-correlations of these channel parameters are analysed based on measurements, and the cross-correlations between the shadow fading, RMS delay spread and m-factor can be clearly observed for LOS condition, whereas the obstruction of NLOS reduces the cross-correlations.
