Abstract
The next wireless communication system will support flexible beamforming and beam-sweeping to realize high capacity demands. This can be achieved with Massive MIMO systems realizing high beamforming gains as well as higher order multi-user multiplexing. Real proof-of-concepts are required to evaluate algorithms and show performance gains. In general, prototyping of M-MIMO systems is challenging, since many transceiver chains have to be calibrated and data streams synchronized. In this paper, we perform measurements in an indoor environment using a real M-MIMO SDR system with 16 active antenna ports. System-level simulations on recorded measurement data highlight downlink throughput results for individual users.
