APPARATUS AND METHOD FOR CANCELLATION OF PARTIALLY OVERLAPPED CROSSTALK SIGNALS

摘要

An apparatus for canceling crosstalk due to the partial overlap of a frequency band and its method are provided to reduce the complexity of calculation required for canceling crosstalk by removing the necessity of using a high sampling frequency. A pre-processor module(210) downwardly transfers an input signal including crosstalk to a baseband. A crosstalk canceling module(220) divides the downwardly-transferred input signal by an interpolation rate, and cancels the crosstalk of the input signal. A post-processing module(230) converts an output of the crosstalk canceling module(220) into a pass band signal. An error feedback processor module(240) receives a remnant crosstalk from the post-processing module(230), executes decimation, and feeds it back to the crosstalk canceling module(220).
