The 5th generation mobile communication system (5G) incorporates the latest technologies such as OFDMA, LDPC codes and millimeter wave in addition to MIMO. In order to evaluate the propagation characteristics of such a complex system, it is very difficult to evaluate the propagation characteristics at multiple frequencies. In this paper, we propose a method for estimating the Datarate of wideband MIMO systems such as 5G using narrowband signals such as CW signals. In this paper, we propose an extension of this method to multiuser systems, and show the effectiveness of this method by applying it to measured data.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
