Channel estimation for multiuser MIMO-OFDM systems based on Kalman algorithms

Abstract: I. IintroductionIt is now widely accepted that multiple input multiple output (MIMO) systems increase the link reliability and/or spectral efficiency of multiuser wireless communications [1]. Moreover, when channel state information (CSI) is available at the transmitter, linear precoding can be used to further improve system performance by tailoring the transmission to the instantaneous channel conditions [2]-[5] while retaining the benefits of alllinear processing. CSI at the transmitter is mandatory in the m… Show more
