Abstract

Future communication systems employing massive multiple input multiple output (MIMO) will not have the ability to use channel state information at the mobile user terminals. Instead, it will be necessary for such devices to evaluate the downlink signal to interference and noise ratio (SINR) with interference both from the base station serving other users within the same cell and other base stations from adjacent cells. The SINR will act as an indicator of how well the pre-coders have been applied at the base station. The results presented in this paper from a 32 x 3 massive MIMO channel sounder measurement campaign at 2.4 GHz show how received bit error rate and error vector magnitudes can be used to obtain a prediction both of the average and dynamically changing signal to interference and noise ratio.
