<p>A method and system is described for use with or in a satellite for compensating for cross coupling of satellite feeder link signals from a first channel of a first linear polarization as received by a first linearly polarized satellite antenna element with adjacent signals from a second channel. The second channel signals are at a generally orthogonal linear polarization. The system includes a second linearly polarized antenna element oriented orthogonal to the first antenna element for sensing the second channel signal, a gain controlled amplifier for reducing the gain of the second channel signal received at the second antenna element in inverse proportion to the sensed amount of cross coupling (depolarization) and adding the reduced gain signals the have been inverted to the first channel signals from said first antenna element.</p> |
