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 11):
A system for wireless communication, the system comprising:\n one or more circuits comprising one or more RF paths, wherein said one or more circuits are operable to:\n receive radio frequency (RF) signals comprising a desired signal and at least one crosstalk signal; \n down-convert the received RF signals; \n determine crosstalk between channels in the received RF signals by calculating complex coupling coefficients between the received RF signals utilizing a de-correlation algorithm across a frequency bandwidth comprising said desired and crosstalk signals, wherein said crosstalk is approximated as linear within said frequency bandwidth for said calculating complex coupling coefficients and said crosstalk is represented as a sum of an average term and a linearly varying term; and \n extract data communicated by said desired signal by utilizing said complex coupling coefficients to cancel the crosstalk between said channels in the received RF signals.
