ABSTRACT:
An adaptive equalizer estimates a channel impulse response h in a channel impulse response estimator and outputs a result to a channel impulse response convertor. The channel impulse response convertor removes interference components from the channel impulse response h, outputs a channel impulse response h' to an equalizer. The equalizer sets up, based on the channel impulse response vector h', internal parameters, and equalizes, based on the internal parameters, reception signals. By configuring as above, distortion by intersymbol interference and a deterioration of reception performance by co-channel interference waves can be prevented.
