- An apparatus for receiving data in a communication system includes: a detection unit configured to calculate power values of a data packet and a ratio of the power values by using a preamble of the data packet in a received signal, and detect the data packet through the calculated ratio of the power values; a control unit configured to calculate a gain compensation value of the detected data packet, and perform an automatic gain control (AGC) on the detected data packet by using the gain compensation value; a compensation unit configured to calculate a DC offset in the received signal, and remove the DC offset from the received signal; and a demodulator configured to demodulate the AGCed data packet.
