Abstract:
1. A method of reducing interference in a satellite communications system defining a feeder link between a Space-Based Component (SBC) and Ground Based Equipment (GBE), the method comprising: determining an error of a received feeder link signal communicated over the feeder link between the Space-Based Component (SBC) and the Ground Based Component (GBE); pre-distorting a first feeder link signal responsive to the error of the received feeder link signal; and transmitting the pre-distorted first feeder link signal over the feeder link between the Space-Based Component (SBC) and the Ground Based Equipment; wherein pre-distorting the first feeder link signal responsive to the error comprises combining a measure of the first feeder link signal with a measure of a second feeder link signal that is correlated with the error of the received feeder link signal.
