摘要： A television signal receiver comprises: a tuner, an optional IF conditioner, an IF distortion canceller, and an IF demodulator. The tuner selects one channel from a radio frequency television signal to generate an intermediate frequency signal. The IF conditioner outputs an IF conditioned signal. The IF distortion canceller cancels a signal distortion in the IF signal or the IF conditioned signal to generate an IF distortion-cancelled signal. The IF demodulator demodulates the IF distortion-cancelled signal to output a baseband signal.

摘要： An equalization method receiving a received sample to generate an equalizer output. A channel profile is first provided, comprising a main path and a plurality of echoes distributed in time domain. Echoes anterior to the main path are precursors, and echoes posterior to the main path are postcursors. The received sample is filtered with a linear equalizer (LE) comprising a plurality of taps to generate an LE output. A slicer slices the equalizer output to generate a sliced sample. The sliced sample is further sent to a decision feedback equalizer (DFE) comprising a plurality of taps to generate a DFE output. Simultaneously, an equalizer span is determined based on the channel profile. The LE output and the DFE output are combined to generate the equalizer output having the equalizer span. The equalizer span is determined by allocating the position of main tap.
