Vector channel modeling and prediction for improvement of downlink signal-to-interference ratio

We analyze the application of the vector channel synthesis and prediction filter introduced by Arredondo et al.. Ray-tracing simulations show that predictions of the downlink channel can result in improvements in signal-to-interference ratio in excess of 10 dB in nonline-of-sight scenarios, compared with beamforming without predictions.
