Propagation Characteristics Measurements for Multi-Site MIMO Systems in Urban Micro-Cellular Environment

Multi-site MIMO (MS-MIMO) technology, where multiple base stations cooperate on the transmission for a user, is expected to improve user throughput at the cell edges. We conducted a propagation measurement campaign assuming MS-MIMO systems in an urban city using three synchronized transmitters. In this paper, several results of measured characteristics are reported, and the performances of MS-MIMO systems are evaluated using the measured data.
