Abstract
An apparatus and a method for compensating for a Transmission (Tx) gain in a transmitter of a wireless communication system are provided. The apparatus includes a Tx Automatic Gain Control (AGC) for generating at least an adjustment value for controlling a Tx gain; a Tx Power Adjust (TPA) controller for generating a compensation value for compensating for Nonlinear Compensate Table (NCT) control information using frequency and temperature changes according to operations of the transmitter and the adjustment value provided from the Tx AGC; and an NCT controller for generating the NCT control information using the adjustment value provided from the Tx AGC, and compensating for the NCT control information with the compensation value output from the TPA controller.
