Abstract: Methods and systems are described for providing end-to-end beamforming. For example, end-to-end beamforming systems include end-to-end relays and ground networks to provide communications to user terminals located in user beam coverage areas. The ground segment can include geographically distributed access nodes and a central processing system. Return uplink signals, transmitted from the user terminals, have multipath induced by a plurality of receive/transmit signal paths in the end to end relay and are relayed to the ground network. The ground network, using beamformers, recovers user data streams transmitted by the user terminals from return downlink signals. The ground network, using beamformers generates forward uplink signals from appropriately weighted combinations of user data streams that, after relay by the end-end-end relay, produce forward downlink signals that combine to form user beams.

Abstract: Strength of a signal received by a low-noise amplifier is controlled depending on strength of a reception signal emitted to a communication satellite by a mobile terminal. A low-noise amplification device provided in the communication satellite comprises: a variable-power attenuation unit which generates an attenuation signal by attenuating the reception signal received in the communication satellite; a low-noise amplification unit which generates an amplification signal by amplifying the attenuation signal with low noise; and a signal control unit which outputs a control signal to the variable-power attenuation unit depending on the attenuation signal, and then adjusts an attenuation of the variable-power attenuation unit.

Abstract: A satellite communications system provides for handovers between spot beams, including communicating (at a ground based terminal) with a non-geostationary satellite constellation using a first spot beam of the non-geostationary satellite constellation and a first beam hopping plan. The ground based terminal changes the communicating with the non-geostationary satellite constellation to use a second spot beam of the non-geostationary satellite constellation and a second beam hopping plan.

Abstract: A satellite is configured to communicate with a ground base station to provide coverage for communication in a first geographic region, and suppress from the communication, interference from a second geographic region. The satellite includes an onboard beamformer (OBBF), feed array and feeder-link antenna. The OBBF is configured to produce first and second spot beams for respective ones of the first and second geographic regions. The feed array is configured to receive first and second signals in respective ones of the first and second spot beams for respective geographic regions. At least portions of the first and second signals carry respective ones of the communication and the interference. The feeder-link antenna, then, is configured to transmit the first signals and second signals to the ground base station that is configured to suppress any of the interference from at least the portion of the first signals carrying the communication.
