Patent ID: 8363701

Claim:
A method for receiving a signal by a mobile terminal in a wireless communication system, the method comprising: maintaining a channel estimation module in an active state; determining an activation time point of an equalizer weight calculation module to calculate a tap coefficient for a main equalizer module, the activation time point of the equalizer weight calculation module being earlier than an activation time point of the main equalizer module; activating the equalizer weight calculation module at the determined activation time point so as to calculate the tap coefficient; activating the main equalizer module so that the main equalizer module can receive the tap coefficient when an operation of the equalizer weight calculation module is completed; detecting a mobile terminal identifier (ID) by demodulating a control signal received over a control channel, activating an interference cancellation module so as to receive a data signal over a data channel when the detected mobile terminal ID corresponds to an ID of the mobile terminal, and controlling the main equalizer module to provide the data signal, which is compensated for by the tap coefficient, from an output of the main equalizer module to a data signal demodulator; and demodulating the compensated data signal in the data signal demodulator.
