Abstract:
Methods and systems for improved cross polarization rejection and tolerating of coupling between satellite signals may comprise receiving radio frequency (RF) signals on a chip, where the RF signals comprising a desired signal and at least one crosstalk signal. The received RF signals may be down-converted to baseband frequencies, and the down-converted signals are converted to digital signals. Crosstalk may be determined by estimating complex coupling coefficients between the received RF signals utilizing a de-correlation algorithm across a frequency bandwidth comprising the desired and crosstalk signals. The down-converted signals may be low-pass filtered and summed with an output signal from a cancellation filter. The complex coupling coefficients may be determined utilizing the de-correlation algorithm on the summed signals, and may be used to configure the cancellation filter. Crosstalk may be canceled in a receiver path from a cancellation filter receiving low-pass filtered down-converted signals from another path.

Claim (Index 26):
The method according to  claim 25 , comprising configuring said cancellation filter utilizing said determined complex coupling coefficients.
