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.
