Kurzfassung englisch:
Models for the wireless channel for massive multiple-input multiple-output (MIMO) communication in the sub-6 GHz frequencies often assume a rich scattering environ- ment. However, measurements in outdoor-to-indoor scenarios indicate a low rank of the wireless channel coefficients matrix. We approximate a measured 70x169 massive MIMO outdoor- to-indoor channel with its sparse representation by applying atomic norm minimization. We further investigate the enhanced resolution in direction of departure and direction of arrival for closely located multipath components compared to conventional beamforming. Finally, we compare the achievable rate for the measured channel with sparse approximated versions.
