Research Abstract

A transmitter side needs channel state information in multi-user MIMO downlinks. In time-varying environments, channels at the actual downlink transmission time are different from estimated channels, which situation causes interference and performance degradation. The purpose of this study was to improve the multi-user MIMO system performance predicting channels at the transmission time.
As for the channel prediction scheme, we examined autoregressive (AR)-model-based prediction and Lagrange extrapolation. We evaluated the MIMO transmission performance using channels obtained in a measurement campaign in indoor environments. It has been shown that the Lagrange extrapolation that is easy to implement can predict channels in the range over 0.1 wavelengths without significant performance degradation.
