Abstract: A method and a satellite gateway for minimizing an impact of a noise floor variation in a spot beam satellite system. A demodulator processes digitized signals from multiple channels. Digitized signals are automatically gain controlled by respective automatic gain control components associated with respective channels. Automatic gain controlled digitized signals are downconverted and provided to a burst processor. The burst processor processes each downconverted signal and provides, with respect to each downconverted signal, an automatic gain control estimate, a code rate, and an inroute number to a processor component. The processor component determines an average automatic gain control value for each inroute, provides automatic gain control references to the respective automatic gain control components, and periodically sends noise map information to satellite terminals served by the satellite gateway. In some embodiments, the automatic gain control values are biased according to corresponding code rates.

Abstract: A device is provided for use with an input signal including a first packet of a first modulation type in series with a second packet of a second modulation type. The device includes a gain adjustment portion and a gain portion. The gain adjustment portion can output a first gain adjustment signal based on the first packet or can output a second gain adjustment signal based on the second packet. The gain portion can output a first signal corresponding to the first packet and can output a second signal corresponding to the second packet. The first signal is based on the input signal and a first gain factor. The second signal is based on the input signal and a second gain factor. The first gain factor is based on the first gain adjustment signal. The second gain factor is based on the second gain adjustment signal.

Abstract: An approach is provided for communicating in a wireless network, such as a point-to-multipoint (PMP) system. A message that contains addressing information corresponding to one of the plurality of terminals is received by a radio terminal. The terminal electronically steers a beam of an antenna in response to the addressing information. The address information may also be used to specify the modulation type and coding level.
