Abstract:
1. A method of cancelling interference from satellite signals received at approximately the same frequency as a desired satellite signal, comprising: receiving a composite signal comprising: coupling a first register within a first adaptive filter to a tap-weight computer; determining within the tap-weight computer an initial weight for each of several tapped outputs from the first interfering satellite signal; loading from the tap-weight computer a first tap-weight vector into the first register to control the amount to be adjusted of interfering signal at each of the tapped outputs from the interfering satellite signal; determining a first error correction of the composite signal based on the output of the first adaptive filter; decoupling the first register and coupling a second register within a second adaptive filter to the tap-weight computer; determining an initial weight for each of several tapped outputs from the second interfering satellite signal; loading a second tap-weight vector into a register within a second adaptive filter to control the amount of interfering signal at each of the tapped outputs from the second interfering satellite signal; and determining a second error correction of the composite signal based on the output of the second adaptive filter.
