  • Terminal initiated intrasatellite antenna handover method
    Publication number: 20110105126
    Abstract: A handover method provides intrasatellite transmitter handover detection and decision using an unbiased weighted Signal Noise Ratio (SNR) estimator based on forgetting factors for SNR monitoring, and a threshold delay is introduced to ensure the reliability of handover decision to prevent undesirable handovers during beam switching.

  • Automatic gain control 16-ary quadrature amplitude modulation subsystem
    Patent number: 7450670
    Abstract: An improved AGC subsystem for preferred use in quadrature amplitude modulation receivers offers improved automatic gain control of received signals in fading channels by generating an error signal only from constellation signal points having large signal-to-noise ratios for increase the signal-to-noise ratio of the gain control error signal for lowering dispersion of symbol signals in the constellation signal space for improving data detection of symbol signals with the improved performance with as much as one dB in the signal-to-noise ratio.
