Abstract:
A satellite radiotelephone system comprising:a space-based component that is configured to receive wireless communications from a first radiotelephone in a satellite footprint over a satellite radiotelephone frequency band; an ancillary terrestrial network that is configured to receive wireless communications from a second radiotelephone in the satellite footprint over the satellite radiotelephone frequency band, the space-based component also receiving the wireless communications from the second radiotelephone in the satellite footprint over the satellite radiotelephone frequency band as interference along with the wireless communications that are received from the first radiotelephone in the satellite footprint over the satellite radiotelephone frequency band; and an interference reducer that is responsive to the space-based component and to the ancillary terrestrial network, and that is configured to reduce the interference from the wireless communications that are received by the space-based component from the first radiotelephone in the satellite footprint over the satellite radiotelephone frequency band, using the wireless communications that are received by the ancillary terrestrial network from the second radiotelephone in the satellite footprint over the satellite radiotelephone frequency band.
