<p>The demodulating apparatus comprises an IF band transversal filter as a forward equalizer, to which an IF band modulated signal is inputted, for equalizing leading (pre-cursor) component of intersymbol interference; a demodulator for receiving the output of the IF band transversal filter to extract a baseband signal; a baseband backward decision feedback equalizer, to which the output of the modulator is inputted, for equalizing lagging (post-cursor) component of intersymbol interference; a first control signal generating circuit for generating tap coefficients of the IF band transversal filter; and a second control signal generating circuit for generating tap coefficients of the decision feedback equalizer. This demodulating apparatus effects sufficient equalization even when severe deep selective fading occurs. <IMAGE></p> |
