Abstract
A method of generating a gain combination of a pre-amplifier of a transmitter in a mobile communication system includes extracting respective pieces of gain combination information about pre-amplifiers of a plurality of sample transmitters among transmitters of the same group, arranging the respective pieces of gain combination information in order and measuring a difference between first output values with respect to adjacent pieces of gain combination information among the arranged pieces of gain combination information, deleting gain combination information that does not conform to linearity of the first output values and rearranging the respective pieces of gain combination information, measuring a difference between second output values with respect to adjacent pieces of gain combination information among the rearranged pieces of gain combination information, extracting second output value compensation parameters with respect to the respective pieces of gain combination information, and extracting common gain combination information about the respective pieces of gain combination information of the sample transmitters by use of the gain combination information, the difference between the second output values, and the second output value compensation parameters.
