Abstract
We consider the crosstalk cancellation
problem when the transmit and receive signal spectrum
are partially overlapped with each other in the
frequency domain. In this case, the use of conventional
crosstalk cancellers may not be practical due to the
computational complexity. When the overlapped
bandwidth of the crosstalk signal is less than the
bandwidth of the transmit signal, the crosstalk
cancellation can be realized efficiently by processing in
the baseband. The use of interpolation and decimation
processing in the baseband makes it possible to realize
the crosstalk canceller with low computational
complexity. The proposed scheme can provide crosstalk
cancellation performance comparable to the
conventional one, while requiring the computational
complexity less than one half the conventional one.
