“…The transceiver architecture of a MIMO channel sounder determines the multiplexing scheme as will be described in the following. Figure 3 shows three possible MIMO channel sounder schemes where basically TDM (time division multiplexing) [23], [26]- [28], FDM (frequency division multiplexing) [38], [39], and CDM (code division multiplexing) [40], [41] schemes or a hybrid method among them can be chosen appropriately.…”

“…First, in order to reduce the implementation cost, a transmitter switching architecture that has a single radio front-end at the transmitter, and a single (fully switching) radio front-end [23], [28] or a complete set of antennas and radio frontends (semi-parallel scheme) [42] at the receiver as shown in Fig. 3(a) is widely employed with a TDM scheme.…”

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 investigated. The authors' group has been involved in a fundamental research project aimed at investigating multipleinput-multiple-output (MIMO) transmission performance and propagation channel properties at microwave frequency above 10 GHz 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 60 GHz and presenting some measurement results in a microcell environment at 11 GHz. Furthermore, this paper identifies challenges in radio propagation measurements, and discusses current/future channel modeling issues as future works.

“…In [9,10], systems were presented based on spherical and semi spherical switched arrays that are capable of measuring radio channels at the receiver while moving; however, the performance in both angular domains was poor. Measurements of the directional propagation effects at both the transmitter and receiver were reported in [11,12], using the Elektrobit PropSound Channel Sounder [13].…”

“…The receiver of the TKK sounder [7] is basically a down converter and sampling unit and all the signal processing, including the correlation of the received signal with the transmission signal, is done in a post processing process. Hence, the post-processing can be easily adjusted for other types of sounding signals.…”
