PREDISTORTER USING MEMORY POLYNOMIAL MODEL, PREDISTORTING METHOD THEREOF, AND SYSTEM INCLUDING THE PREDISTORTER

摘要

PURPOSE: An inlet distortion apparatus, inlet distortion method, system including the same are provided to constitute simplified memory polynomial models by combining basic sections according to feedback results for output signals of a non-linear apparatus. CONSTITUTION: An inlet distortion filter(1100) selects one or more basic sections of plural basic sections according to selecting values. The inlet distortion filter constitutes memory polynomial models. The inlet distortion filter distorts input signals by using the memory polynomial models. A selection module(1140) determines the selecting values according to feedback results for output signals of a non-linear apparatus(1200).
