ABSTRACT:
In an OFDM receiver the complex values of predetermined pilot sub-carriers are compared with expected values to determine pilot distortion values for those sub-carriers. The phases of the differences between successive values are determined, and then the rate at which these phases change with respect to sub-carrier frequency is determined. Data distortion estimates for other sub-carriers can be calculated by interpolation of the pilot distortion values such that the data distortion estimates have a phase which substantially complies with the determined rate.
