传统移动蜂窝频段的严重短缺,使得高频段的开发与利用受到越来越多的关注与研究。采用了基于PN序列的时域测量系统,在15 GHz频段下对会议室环境的直视场景(LOS)和非直视场景(NLOS)进行了信道测量,分析了其大尺度衰落特性,得到了距离和路径损耗的关系,并计算得出室内会议室环境下的路径损耗指数和阴影衰落因子。测量采用了增益为27 dBi的双脊波导天线和全向天线,通过改变发射天线水平角得到某个距离下的测量数据,分析了特定场景下接收功率随角度的变化特性。
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.
