MULTI-SATELLITE COMMUNICATION SYSTEMS

摘要

Satellite communication systems and methods are disclosed. The communication system may include a gateway in communication with two satellites. The satellites are configured to receive polarized signals from a first plurality of users and orthogonally polarized signals from a second plurality of users. The signal may be an OFDM signal. The subscriber terminals may include an antenna pointed toward at least one of the satellites and configured to receive OFDM signals. The OFDM signal time is proportional to the longest transmission time difference of all subscriber terminals within the geographic area serviced by the satellites. Various other communication schemes are disclosed utilizing multiple satellites are also disclosed.
