In recent years, there has been a spurt of activities to explore the terahertz (THz) band comprising frequencies above 100 GHz to support high data rates and low latency applications. In this light, the current study presents an overview of a novel in-house channel sounder operating at 300 GHz followed by elaboration of a high-resolution double-directional channel measurement performed in an office environment. The letter validates the sounder, wherein the measurement accuracy is assessed by comparing the results from the campaign and ray-tracing (RT) simulation. The measurement system is expected to contribute to the advancement of THz communications research.

In order to utilize higher frequency bands above 6GHz, 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 investigated. The authors' group has been involved in a fundamental research project aimed at investigating multiple-input-multiple-output (MIMO) transmission performance and propagation channel properties at microwave frequency above 10GHz from 2009 to 2013, and since then they have been conducting measurement and modeling 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 60GHz and presenting some measurement results in a microcell environment at 11GHz. Furthermore, this paper identifies challenges in radio propagation measurements, and discusses current/future channel modeling issues as future works.
