为了利用6 GHz以上的更高频带，这是第五代移动的系统中的重要技术挑战，应彻底调查各种部署场景中的无线电传播信道特性。作者小组还参与了一项基础研究项目，旨在研究2009年至2013年微波频率高于10 GHz时的多输入多输出（MIMO）传输性能和传播信道特性，此后他们一直在进行高频带的测量和建模活动。本文通过介绍所研制的11 GHz和60 GHz高频段MIMO信道探测器，以及在11 GHz微小区环境下的测量结果，对信道建模、多维信道探测、传播信道测量、分析和建模的全过程进行了全面的介绍。此外，本文还指出了无线电传播测量中的挑战，并讨论了当前/未来的信道建模问题作为未来的工作。
SUMMARY In order to utilize higher frequency bands above 6 GHz, which is an important technical challenge in fifth generation mobile systems, radio propagation channel properties in a large variety of deployment scenarios should be thoroughly in-vestigated. The authors’ group has also been involved in a fun- damental research project aimed at investigating multiple-input-multiple-output (MIMO) transmission performance and propa- gation channel properties at microwave frequency above 10 GHz from 2009 to 2013, and since then they have been conducting measurement and modeling activities for high frequency bands. This paper aims at providing comprehensive tutorial of a whole procedure of channel modeling; multi-dimensional channel sounding, propagation channel measurement, analysis, and modeling, by introducing the developed MIMO channel sounders at high frequency bands of 11 and 60 GHz and presenting some mea- surement results in a microcell environment at 11 GHz. Further-more, this paper identifies challenges in radio propagation mea- surements, and discusses current/future channel modeling issues as future works.
