论文摘要
需要表征毫米波无线通道以促进将来完全连接的车辆通信。为了研究富含多路径的车辆传播环境的迅速变化的性质，需要快速毫米波通道。我们提出了一种通道音响器设计，能够通过同时使用四个分阶段阵列在6.25毫秒的6.25毫秒内覆盖Azimuth的360度，并在高程中覆盖60度。通道测量值伴随着高分辨率的定位和视频数据，可以在发射器或接收器或两者都在移动时进行通道。在得克萨斯州奥斯汀的多个城市地点，在多个城市地点进行了频道探测活动。初步结果表明，接收器的光束选择可以将有效的路径指数降低至1.6，而视线范围为2.25。
Characterization of the millimeter wave wireless channel is needed to facilitate fully connected vehicular communication in the future. To study the multipath-rich, rapidly varying nature of the vehicular propagation environment, fast millimeter wave channel sounders are required. We present a channel sounder design capable of covering 360 degrees in azimuth and 60 degrees in elevation with 200 individual beam directions in 6.25 ms by using four phased arrays simultaneously. The channel measurements are accompanied by high resolution positioning and video data, allowing channel sounding to be conducted while either the transmitter, or the receiver, or both are moving. Channel sounding campaigns were conducted at multiple urban locations with light traffic conditions in Austin, Texas. Preliminary results show that beam selection at the receiver can lower the effective pathloss exponent to 1.6 for line-of-sight and 2.25 for non line-of-sight.
