Abstract
An orbiting multiple access transceiver communicates with terrestrial mobile stations which are also capable of communicating with terrestrial base stations. The multiple access transceiver is configured to sample a signal when a terrestrial mobile station of interest is not transmitting to produce a sample signal. The sample signal may be processed to produce an out-of-phase signal that may be applied to a signal when the terrestrial mobile station of interest is transmitting to produce a clearer signal from the terrestrial mobile station of interest.
Claims19
A method of processing signals received by a signal processor of an orbital base station received from a plurality of terrestrial mobile devices, the terrestrial mobile devices also capable of communicating with terrestrial base stations, the method comprising:
- receiving, by a transceiver, a first signal from some of the terrestrial mobile devices;
- reducing, by a filtering module as part of the signal processor of the orbital base station, a first portion of the first signal, wherein the first portion is due to a transmitting plurality of the terrestrial mobile devices that are communicating with one or more of the terrestrial base stations;
- producing a filtered signal comprising a second signal from a target mobile device communicating with the orbital base station, the target mobile device being distinct from the transmitting plurality;
- and
- demodulating, by a signal demodulator, the filtered signal to produce a demodulated signal corresponding to the second signal from the target mobile device.
