摘要

我们研究了蜂窝宽带固定无线应用的典型信道。建立了基于双元接收天线结构的双元发射测量系统，在双天线极化和发射分离的郊区环境下进行了测量。我们给出了k因子、交叉极化鉴别(XPD)和多普勒谱的结果。我们的研究结果解决了距离和天线高度对k因子和XPD的影响。我们还讨论了固定无线信道的特性，并描述了它的多普勒频谱。

Measurement and characterization of broadband MIMO fixed wireless channels at 2.5 GHz

We study the channel typical for cellular broadband fixed wireless applications. A measurement system for a two-element-transmit by two-element-receive antenna configuration was built, Measurements were conducted in a suburban environment with dual antenna polarization and transmit separation. We present results on K-factor, cross-polarization discrimination (XPD) and Doppler spectrum. Our results address the influence of distance and antenna height for K-factor and XPD. We also comment on the properties of a fixed wireless channel and describe its Doppler spectrum.
