SYSTEM AND METHOD FOR CANCELLING INTERFERENCE SIGNAL USING DIGITAL SIGNAL PROCESSING

摘要

PURPOSE: A system and a method for cancelling an interference signal using digital signal processing are provided to be applied to various environments which need an ICS(Interference Cancellation System) repeater. CONSTITUTION: An adaptive filter sub block operating unit(103) generates a feedback signal by using an assigned sub block. A feedback signal generating unit(109) adds the feedback signals generated by the adaptive filter sub block operating unit. The feedback signal generating unit generates a final feedback signal. An original signal detecting unit(107) subtracts a final feedback signal generated in the feedback signal generating unit and an output signal of an A/D converter. The original signal detecting unit detects an original signal.
