Third dimension for measurement of multi user massive MIMO channels based on LTE advanced downlink

We characterize third-dimension (3D) of channel measurements based on two dimension channel model with fully-synchronize propagation of first time LTE-A multi-user centralized multiple-input, multiple-output(MU-MIMO) with sixteen transmitter antennas and three users. By exploiting the spatial correlation of signals originating from neighboring receiving antennas, there is a need for an accurate and actual radio propagation model around Shanghai Jiao Tong University (SJTU) campus network. The paper describes our real-time implementation and several test results are reported in the forthcoming LTE-A release. Measurements show the experimental characteristics of the sensitivity of the spatial correlation with the different array of polarization antennas between users that can be well approximated by a Kronecker production. In addition; we analyze the capacity of MU-MIMO systems to explain the achievable capacity rate of current LTE-A antenna configuration at the user side.
