Disclosed is an apparatus for transmitting complex signals in a wireless communication system. The present invention, there is provided a method for controlling gain according to a magnitude change of output signals in a polar transmitter including an amplification unit having two or more amplification degrees, the method includes processes to control an output level of a modulated signal when a output-required power of transmission signals are less than a predetermined threshold value, and to perform a basic amplification through the amplification unit; to amplify the amplification unit at a first amplification level when the output-required power of the transmission signals is equal to or greater than a predetermined first threshold value and is less than a predetermined second threshold value; and to amplify the amplification unit at a second amplification level when the output-required power of the transmission signal is equal to or greater than the second threshold value.
