Abstract

Wideband channel measurements have been performed at 5.25 GHz in hotspot areas in Beijing with a multiple-input multiple-output channel sounder. The measured scenarios include indoor line-of-sight (LOS) and non-line-of-sight, and outdoor LOS and obstructed-line-of-sight. Statistical results of channel characteristics are presented which include the path loss models, root mean square delay spread, circular azimuth spread and average envelope correlation with respect to antenna separation. Comparative analysis of the results are provided. These information are of significance for the design and performance evaluation of international mobile telecommunications (IMT)-advanced systems.
