Abstract [en]

MIMO systems have been widely studied in recent years, and several characteristics of the radio channel have been studied and analysed. One aspect of great interest is the analysis and optimization of parameters regarding the base station when multiple antennas are used at the receiver and the transmitter. Moreover, when not only the link-level but also the system- level is to be studied, the system performance when multiple users are considered is of importance. By using the channel measurements obtained with different base station locations and multiple routes in an indoor scenario, we present in this paper the results for a multi-user MIMO system when different possibilities in location and signal combination or cooperation for base stations are compared. Results are shown in terms of sum-capacity, which is evaluated for different transmit methods (with and without CSI) and base station locations, and it is compared with the capacity in a single user system (with and without interference).
