摘要： Systems, devices, processors, and methods are described for the transmission and reception of broadband signals between a gateway and subscriber terminals via satellite. In one set of embodiments, a wireless signal is generated and transmitted including a series of frames including a physical layer header and payload. A sub-channel identifier may be included in the physical layer header to identify the sub-channel for the payload, and allow for various novel filtering techniques at the subscriber terminal. The frames may be generated to be of substantially equal duration. Novel subscriber terminal configurations are described to leverage this formatting.

摘要： A method is presented for communicating data in a multibeam satellite system utilizing frequency re-use. The method comprises establishing uplink service beams and downlink service beams between a satellite and a plurality of subscriber terminals. A plurality of the uplink service beams are transmitted to the satellite by re-using at least one common uplink frequency channel. A plurality of the downlink service beams are transmitted from the satellite by re-using at least one common downlink frequency channel. The method further comprises establishing at least one uplink feeder beam and at least one downlink feeder beam between the satellite and a gateway terminal. The at least one uplink feeder beam is transmitted to the satellite by further re-using the at least one common uplink frequency channel. The at least one downlink feeder beam is transmitted from the satellite by further re-using the at least one common downlink frequency channel.

摘要： A communication technique based on direct sequence spread spectrum signaling employs, for all users sharing an access channel, a single spreading code that has a duration sufficiently longer than the symbol length that the likelihood of confusion between users is minimized if not eliminated. The length of the spreading code is sufficiently long that contention events can occur only when two bursts occur at the receiver within one chip time of one another.
