Analysis of Millimeter-Wave Channel Characteristics Based on Channel Measurements in Indoor Environments at 39 GHz

This paper analyzes channel characteristics of millimeter-wave (mm-wave) at 39 GHz in indoor environments based on channel measurements in a conference room and a lobby. Statistical results of channel large-scale fading characteristics including path loss (PL), shadow fading (SF) and small-scale fading characteristics like K-factor, root mean square (RMS) delay spread (DS) and RMS angular spread (AS) are presented. Furthermore, effects of different environments on the channel characteristics are investigated. In addition, differences between our measurement-based channel model parameters and those of the 3GPP channel model are discussed. The comparative analysis results reveal that channel characteristics are highly related with the measured environments; a complex environment with abundant reflectors has large RMS DS and RMS AS but small K-factor due to rich scattering.
