Abstract
The present invention is related to a partially overlapped single-carrier crosstalk signal cancellation method and an apparatus using the same. For this purpose, the present invention provides a crosstalk canceller including a pre-processor for frequency down-shifting an input signal, a crosstalk signal cancellation module for canceling the crosstalk signal by dividing the input signal by an interpolation ratio, a post-processor for converting an output of the crosstalk signal cancellation modulation into a passband signal, and an error feedback processor for performing a decimation operation on a residual crosstalk signal and feeding backing the decimated residual crosstalk signal to the crosstalk signal cancellation module. In addition, the present invention provides a crosstalk signal cancellation method for performing interpolation and filtering operations by frequency down-shifting an input signal including a crosstalk signal to a baseband and decimating a residual crosstalk signal by frequency-shifting to an original signal frequency.
