PURPOSE: An apparatus and a method for receiving a signal suitable for a time varying channel are provided to accurately predict the characteristic of a time-delayed channel and recover original user information using the predicted characteristic of the channel. CONSTITUTION: The first channel characteristic estimating unit(44) estimates the first delay characteristic signal for indicating a delayed characteristic of a channel from a recovered transmitting signal and a receiving signal, and outputs the estimated first delay characteristic signal. The first channel characteristic predicting unit(42) decimates the first delay characteristic signal, predicts characteristic values of the channel from the decimated result, interpolates the predicted characteristic values, and outputs the interpolated result as the first prediction characteristic signal for indicting the predicted characteristic of the channel. The first receiving unit(40) estimates a decision value from the first prediction characteristic signal and the receiving signal, recovers the transmitting signal from the estimated decision value, and outputs the recovered transmitting signal to the first channel characteristic estimating unit(44).
