We address pilot-symbol aided channel estimation (PACE) for orthogonal frequency division multiplexing (OFDM) based systems, with multiple transmit antennas. An approach is presented which estimates and separates NT superimposed signals, corresponding toNT transmit antennas, in two dimensions. More specifically, we extend the concept of using two one dimensional (1D) estimators, instead of a truly two dimensional (2D) estimator to MIMO-OFDM systems, by dividing the estimation as well as the… CONTINUE READING
