ABSTRACT:
In a communication system, an apparatus for receiving a signal transmitted through a channel having time-varying characteristics and for restoring original user information included in the received signal, preferably includes: a first channel characteristic estimator for estimating a signal representing the delay characteristic of the channel; a first channel characteristic predictor for decimating the estimated signal applied thereto, for predicting the characteristic values of the channel, for interpolating the predicted channel characteristic values, and for outputting the interpolated result as a first predictive characteristic signal; and a first receiver for generating a decision value from the first predictive characteristic signal and the received signal, restoring the transmitted signal using the estimated decision value, and outputting a restored transmitted signal, which is fed back to the first channel characteristic estimator.
