PURPOSE: A method and a system for tacking a face from a receiver which uses a multiple face tracking technique are provided to enhance the reception performance of a receiver according to the removal of face noise. CONSTITUTION: A demodulator demodulates a radio frequency signal which is received in order to generate coded symbols and un-coded symbols. A decoder decodes the coded symbols. A plurality of symbol decisions related to the received radio frequency signals is generated. A critical value of phase tracking is determined based on mean square error. Each S-curve(900) is indicated as a linear slope for QAM face tracker.
