摘要
Methods and apparatus are provided for wireless channel estimation using interpolation elimination in the Eigen domain. Channel components at known OFDM symbol locations are interpolated to other OFDM symbol locations. Methods and apparatus are provided for interpolating in the Eigen domain between reference signals (i.e., training signals) to estimate the equalizer coefficients with a reduced complexity. In particular, one aspect of the present invention performs the required interpolation before a required matrix inversion in the Eigen domain.
