优于Rician：将毫米波信道建模为具有漫射功率的双波
Better than Rician: Modelling millimetre wave channels as Two-Wave with Diffuse Power
摘要：
这一贡献提供了实验证据的两波与扩散功率（TWDP）衰落模型。我们已经进行了两次室内毫米波测量活动，在两个链接端定向喇叭天线。一个喇叭天线安装在我们实验室的一个角落里，而另一个是可操纵的，扫描方位角和仰角。我们的第一个测量活动是基于7 GHz带宽的标量网络分析。我们的第二次测量活动获得了幅度和相位信息，另外还在空间的几个位置进行了定向采样。%此第二次测量活动限于2 GHz带宽。我们应用赤池的信息准则来决定是否Rician衰落充分解释的数据或广义TWDP衰落模型是必要的。我们的研究结果表明，TWDP衰落的假设是有利于莱斯衰落的情况下，可操纵天线指向反射物体或在视线稍微错位。我们证明了TWDP衰落在几个不同的域，即，频率，空间和时间。
英文摘要：
This contribution provides experimental evidence for the two-wave with diffuse power (TWDP) fading model. We have conducted two indoor millimetre wave measurement campaigns with directive horn antennas at both link ends. One horn antenna is mounted in a corner of our laboratory, while the other is steerable and scans azimuth and elevation. Our first measurement campaign is based on scalar network analysis with 7 GHz of bandwidth. Our second measurement campaign obtains magnitude and phase information, additionally sampled directionally at several positions in space. %This second measurement campaign is limited to 2 GHz bandwidth. We apply Akaike's information criterion to decide whether Rician fading sufficiently explains the data or the generalized TWDP fading model is necessary. Our results indicate that the TWDP fading hypothesis is favoured over Rician fading in situations where the steerable antenna is pointing towards reflecting objects or is slightly misaligned at line-of-sight. We demonstrate TWDP fading in several different domains, namely, frequency, space, and time.
