Abstract
Systems and methods for canceling cross-coupled satellite signals in a LNB IC include receiving a first satellite signal at a first input of the LNB IC and filtering the first satellite signal using a first adaptive filter, the first adaptive filter having first filter coefficients; combining the adjusted first satellite signal with a second satellite signal received at a second input of the LNB IC to generate a first combined satellite signal; measuring the total output power of the combined satellite signal; changing the filter coefficients of the first adaptive filter; remeasuring the total output power of the first combined satellite signal after the changing of the first filter coefficients to determine whether the total power of the first combined satellite signal has decreased.
