In this work we evaluate urban macro single input multiple output (SIMO) channel measurement performed at 3.7 GHz in Berlin city. In the evaluation we focus on spatial correlation of multi-user channels for varying user densities and distributions in line of sight (LOS) and non line of sight (NLOS) scenarios Therefore, we calculate the correlation matrices, i.e. the covariance matrix of the macro-BS antenna across subsequent channel samples in time. In addition, we estimate the Shannon sum-rate and user data rate distributions for different antenna configurations to clarify fifth generation (5G) performance gains due to spatial multiplexing in a realistic environment.
