APPARATUS AND METHOD FOR COMPENSATING FOR NONLINEARITY IN PORTABLE COMMUNICATION TERMINAL

摘要

An apparatus and method for compensating for nonlinearity of a portable communication terminal are provided. The apparatus includes a modem for modulating Transmission (Tx) data, a Digital Pre-Distortion (DPD) mode controller for obtaining power level information and for determining a power on/off state of a DPD unit by using the obtained information in the Tx mode, and the DPD unitfor outputting the modulated data input from the modem without performing a DPD operation when power is off, and for outputting the modulated data input from the modem by performing the DPD operation when power is on.
