Apparatus and method for canceling noise in wireless transceiver

摘要

A method of canceling noise of a reception module in a wireless transceiver including the steps of determining a filtering band using channel information; generating a switching control signal, selecting a filter to perform filtering according to the determined filtering band; and switching a receive signal received through an antenna of the reception module to the selected filter to perform the filtering using the switches controlled by the switching control signal; and filtering the receive signal using the selected filter. Accordingly, cross modulation (CM) noise of the reception module is canceled.
