The multi cell channel estimator(410) uses the pseudo noise codes and the filtered signal and estimates channel estimating value about the cells. The multi cell adaptive equalizer uses the channel estimation value, models a signal transmitted from the cells and similar random signals and generates a filter coefficient. An equalizer finite impulse response filter(170) uses and equalizes the filtered signal and the filtered coefficient.
