Abstract: An apparatus for beam selection for a multibeam satellite communications system including a VSAT with a remote satellite dish for sending and receiving RF signals and processor for calculating a normalized distance metric for user spot beams, selecting the user spot beam with the lowest normalized distance metric, and finding an outroute on the selected user spot beam using the remote satellite dish.
Abstract: A receiver is used with third code blocks based on first code blocks, second code blocks, and a planning code block. The first code blocks are associated with a first sequence number and modulated with a first modulation scheme. The second code blocks are associated with a second sequence number and modulated with a second modulation scheme. The planning code block associates the third code blocks with the first code blocks and the second code blocks. The receiver includes a de-multiplexing portion, which includes a code block selector and a look up table, that outputs a de-multiplexed signal based on the third code blocks. The code block selector selects a code block from the third code blocks to output as the de-multiplexed signal based on entries in the look up table. The receiver also includes a recovery portion that outputs received code blocks based on the de-multiplexed signal.
Abstract: A method of providing a high symbol rate communication system with reduced overhead bandwidth includes calculating a minimum feasible aperture length at a network operations center, setting a hub demodulator subsystem to use an aperture length calculated from the minimum feasible aperture length, broadcasting the aperture length to a VSAT, and receiving an inroute data stream from the VSAT utilizing the aperture length.

Abstract: A two-way satellite communication system is disclosed. A transceiver transmit signals over a return channel to a satellite and receives signals over a downlink channel from the satellite. A hub communicates with the transceiver over the return channel, wherein the hub provides connectivity between the transceiver and a packet switched network.
