摘要： An apparatus and a method for generating statistical signals having a characteristic similar to an input signal of a receiving apparatus to determine an optimized filter coefficient through an adaptive equalization algorithm are provided. The apparatus includes a channel estimator, a statistical signal generator, and an adaptive algorithm processor. The channel estimator estimates a channel of a reception signal. The statistical signal generator generates a plurality of signals having the same characteristic as that of a reception signal using a channel determined through a channel estimation process. The adaptive algorithm processor performs an adaptive equalization algorithm using the plurality of generated signals to determine an optimized filter coefficient.

摘要： A mobile terminal includes a channel estimation module that is maintained in an active state. A controller determines an activation time point of an equalizer weight calculation module for calculating a tap coefficient. The activation time point is earlier than an activation time point of a main equalizer module, and activates the equalizer weight calculation module at the activation time point so as to calculate the tap coefficient. When the equalizer weight calculation module's operation is completed, the controller activates the main equalizer module, detects a mobile terminal ID, activates an interference cancellation module, and controls the main equalizer module to provide a data signal demodulator with the data signal compensated for by the tap coefficient. A demodulator demodulates the compensated data signal.
