Massive MIMO Radio over the Air Phase Error Measurement

Abstract

The objective of this bachelor’s thesis was to find a way to measure Nokia’s massive MIMO radio’s phase error over the air and then execute these measurements. These measurements were executed in Nokia’s OTAVA test environments. 5G and beamforming are covered in the theory part of the thesis. As a result of this thesis, it is possible to perform phase calibration for a device under testing in an OTA chamber that will allow a more precise calibration and therefore more accurate results. This calibration process would have been the next step for this research but for this thesis there was not enough time.
