APPARATUS AND METHOD FOR DIGITAL UP CONVERTER IN MOBILE COMMUNICATION SYSTEM

摘要

PURPOSE: A device and a method for digital up converter in a mobile communication system are provided to variably control the decimation rate and the interpolation ratio through the frequency clock according to the frequency bandwidth of a inputted signal, thereby supporting various frequency bandwidth signals.;CONSTITUTION: An SIL(Selectable Input Logic)(300) receives a signal form a channel card. The SIL performs decimation at decimation rate. The decimation rate becomes variable according to a frequency bandwidth of the inputted signal. A CDL(Clock Distribution Logic)(310) controls a clock frequency of each filter. A filter logic(320) performs channel filtering about the decimated signal. The filter performs interpolation at an interpolation rate. The interpolation rate becomes variable according to the frequency bandwidth of the inputted signal.;COPYRIGHT KIPO 2010
