ABSTRACT:
An equalizing apparatus for an orthogonal frequency division multiplexing (OFDM) wireless communication receiving system includes a channel estimation block, a first equalizer, and an error compensation block. The channel estimation block performs channel estimation by extracting a pilot signal from a signal supplied to the first equalizer. The first equalizer performs first channel equalization based on the channel estimation from the channel estimation block. The error compensation block outputs an error compensation value of the first equalizer, based on data signals from the first equalizer. The error compensation value may be used by the first equalizer and/or a second equalizer. Related methods and computer program products are also described.
