A Dynamic Dual-Link Wideband MIMO Channel Sounder for 5.3 GHz
In this paper, the authors present and evaluate the performance of a dynamic dual-link wideband Multiple-Input - Multiple-Output (MIMO) channel sounder. The channel sounder can simultaneously measure two wideband dual-polarized links, each with a MIMO matrix size of 30 ? 30 and 30 ? 32. Multilink MIMO systems, including multiuser and cooperative MIMO, are essential parts of future high-throughput wireless local area networks and fourth-generation cellular systems. To fully understand such systems, the dynamic characteristics of multilink MIMO channels have to be measured.
