Abstract In this paper, a Kalman‐filter‐based, vector autoregressive (VAR) model is used to forecast mobile user uplink spatial signatures and improve downlink signal‐to‐interference ratio in time‐division duplex (TDD) systems. Results are presented from computational electromagnetic (CEM) simulations of a smart antenna system operating at 1.8 GHz in an urban microcellular environment. © 2002 Wiley Periodicals, Inc.
