A wireless communication system ( 100 ), method, and base station ( 112 ) are provided for optimizing performance of a base station receiver ( 120 ). The method includes selecting an interpolation matrix ( 216 ) specially tailored for particular channel characteristics from a pre-defined set of interpolation matrices ( 218 ), and using the selected interpolation matrix in the channel estimation, and applying the derived channel estimates for the data subcarriers to an equalizer ( 118 ) as a set of weights. The interpolation matrix ( 216 ) is selected by using the matrix corresponding to a received channel profile information, or by monitoring a performance metric ( 212 ) while using each interpolation matrix of a pre-defined set of matrices in the channel estimation and applying the derived channel estimates for the data subcarriers as a set of weights to the receiver equalizer ( 118 ) and selecting the matrix resulting in best performance.
