| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this study, we develop a versatile multi-link MIMO channel sounding sensor network based on software-defined radios (SDRs). Each radio has a center frequency of 4.85 GHz, a bandwidth of 100 MHz, and a delay time resolution of 10 ns. It can accommodate a large number of antennas using a switched antenna scheme; further, by associating multiple software radios, it can configure a multi-link MIMO measurement and obtain the synchronized channel responses in a short time. It is suitable for various purposes of channel measurements, such as distributed massive MIMO, cell-free MIMO, localization, and sensing. This paper presents the design and implementation of the developed system and verifies the synchronized operation through laboratory tests. Then, the usability is demonstrated through an example measurement for indoor device-free localization (DFL). | |
