Apparatus and method for receiving signal using rake receiver and equalizer in wireless communication system

An apparatus for selecting a receiver for demodulating a reception signal at a reception end including a plurality of receivers, the apparatus comprising:

• a Signal-to-Noise Ratio (SNR) determiner for determining a mean and a standard deviation of SNRs of the receivers;
• a Doppler frequency estimator for estimating a Doppler frequency;
• and
• a microprocessor for determining a statistical value of a modulation order of subframes received in advance, for determining SNR estimation values of the receivers based on the determined mean and standard deviation of the receivers, the estimated Doppler frequency, and the determined statistical value of the modulation order of the received subframes, for selecting one receiver having a largest SNR estimation value among the determined SNRs of the receivers, and for controlling the selected receiver to demodulate a signal received.
