Abstract

The millimeter wave channel at 60 GHz for line-of-sight small cell scenarios was examined through analysis of the measured data using a wideband channel sounder. Full polarimetric directional data obtained at 3 different locations for which the emulation of small cell base-station (transmitter) antenna is at the height of 5 m from the ground floor, where the user-equipment (receiver) is located at 10 locations with different distances between 5 m to 50 m from the base-station. The base-station antenna is as wide to illumitate the small cell whereas at the user-equipment side a 5° beamwidth narrowbeam antenna is used to obtain the directional channel impulse response with high resolution in azimuth-of-arrival and delay. The analysis of the measured data confirms the dominance of the line-of-sight component with small root-mean-squared (RMS) values for delay. Few dominant scatterers can be observed at each environment which increase the delay and angular spread values.

60ghz小小区传播信道毫米波的时延和方位角传播

通过使用宽带信道测深仪分析测量数据，对60 GHz毫米波信道用于视距小蜂窝场景进行了研究。在3个不同地点获得的全极化方向数据，其中仿真小蜂窝基站(发射机)天线位于距地面5米的高度，其中用户设备(接收机)位于距离基站5米至50米不等的10个地点。基站天线的宽度与照亮小小区相同，而在用户设备侧，使用5°波束宽度的窄波束天线来获得定向信道脉冲响应，在到达方位和延迟方面具有高分辨率。对测量数据的分析证实了具有小均方根(RMS)延迟值的视距分量的优势。在每个环境下都能观测到少数优势散射体，这增加了延迟和角扩展值。
