| Summary: | The shortage of traditional mobile cellular band makes the development of higher frequency paid more and more attention. The time domain measurement system based on PN sequence was used to measure propagation characteristics of the line-of-sight（LOS）and non-line-of-sight（NLOS）scenarios of conference room at 15 GHz. The channel large scale fading characteristics and the relationship between distance and path loss were analyzed，and path loss exponent and the shadow fading standard variance were calculated. In the measurement，one double ridged guide antenna with 27 dBi gain and one omni antenna were used. Through changing azimuth angles in transmitting terminal in the measurement points，the relationship between received power and different angles were analyzed. |
