Abstract
Apparatus and method for controlling the crosspolarization of signals in a satellite communications, frequency reuse system. Each earth station in the system includes one crosscoupling network that compensates for the crosspolarization of signals transmitted by such earth station uplink to the satellite due to the propagative medium around such earth station, and an adaptive feedback control system having another crosscoupling network that compensates for the crosspolarization of signals received from the other earth stations due to such propagative medium around such earth station.
