PURPOSE: A mobile communication system and a method for processing a signal in the mobile communication system, particularly for enabling a receiver to accurately detect a signal transmitted from each transmission antenna used in a transmitter, are provided to give a large gain to uplink for which a PAPR(Peak-to-Average-Power Ratio) is important by reducing the amount of data transmitted to uplink. CONSTITUTION: A transmission terminal including multiple transmission antennas(antenna 1-antenna M) adds a CRC(Cyclic Redundancy Check) signal to a signal to be transmitted through each transmission antenna and transmits it to a receiving side. A receiving terminal of the receiving side including multiple reception antennas determines whether signals having the CRC signal received from the sending side have an error. The receiving terminal collects data transmitted from each transmission antenna of the sending side, checks the CRC signal included in each data to determine whether it has a transmission error, and feeds back corresponding information to the sending side.
