  • Publication number: 20110028087
    Abstract: A system for enabling use of ultra-small aperture terminals in satellite communications is provided. The system comprises a transmitter configured to receive an input signal having information, a bandwidth, and an amplitude, replicate the input signal into two or more replications of the input signal, convert each of the two or more replications to have a frequency tuned to two or more corresponding satellite transponders while maintaining the bandwidth and all the information of the input signal, and combine the two or more replications into a single uplink signal. A transmit antenna is configured to transmit the uplink signal to the two or more satellite transponders.

  • Patent number: 7522877
    Abstract: The reduction of echo noise in satellite communications includes receiving an aggregate signal from multiple remote stations, where the aggregate signal includes a transmit signal, whose bandwidth is in the range of 0.1 MHz to 66 MHz, is previously sent from a hub to the multiple receiving stations, computing a scaled, delayed and distorted replica of the transmit signal and using the replica to compensate for satellite transponder nonlinearities and reduce echo noise interference from a received aggregate signal received by the hub from the multiple remote stations.
