Abstract
A method for communication includes receiving first data timed by a first clock and receiving a signal including second data timed by a second clock, which is independent of the first clock, and generating a stream of data samples corresponding to the second signal. The received first data are resampled responsively to a time-varying phase shift between the first and second clocks to generate resampled data timed by the second clock. The resampled data are applied in estimating and subtracting an alien crosstalk component from the stream of data samples.
