Abstract: The present invention relates to a digital pre-distortion apparatus. The digital pre-distortion apparatus comprises: an input delay unit which delays processing of input data as many as the order of a memory; a constant storing unit storing constant numbers of an polynomial expression corresponding to the order of the memory; a digital pre-distortion unit performing an operation using the input data through the input delay unit and the constant numbers of the polynomial expression corresponding to the order of the memory; and an addition unit storing an output of the digital pre-distortion unit, adding a number of the order of the memory to the output a time period of the order of the memory later, and outputting a result of the addition. According to the present invention, the digital pre-distortion apparatus can be implemented using hardware resources at the minimum. Thus, an increment in the hardware resources due to an extension of the order of the memory can be minimized when the digital pre-distortion apparatus considering memory effects is implemented.

Abstract: PURPOSE: A digital pre-distortion device and a method thereof are provided to simultaneously achieve high-linearity and high-efficiency. CONSTITUTION: A DPD(Digital Pre-Distortion) algorithm execution unit(120) calculates the maximum output value and average output value of an output signal for an input signal of a power amplifier during a predetermined period. The DPD algorithm execution unit obtains the reversed function of the output function based on a reference value between an average input value and a maximum input value. A pre-compensation device(110) distorts a source input signal by using information corresponding to the reversed function of the output signal. The pre-compensation device inputs the pre-distortion signal as an input signal of the power amplifier.
