Abstract: An adaptive transmit power control process enables the uplink transmit power of a user terminal to be adjusted based on a scan angle of the antenna for the user terminal. The antenna periodically reports the scan angle to the user terminal, and a current maximum transmit power for the user terminal is determined based on the scan angle. The current maximum transmit power is then used as the basis for determining an allocation of resources to the user terminal. The transmit power control process enables resources to be assigned as needed across multiple carriers and enables a power spectral density of a user terminal to be adjusted based on nominal and offset transmit power parameters.

Abstract: Various arrangements for performing transmodulation of a forward feeder link are presented. A first data stream and a second data stream can be modulated into a higher-order modulation forward feeder link having a higher-order digital modulation scheme. A satellite can receive the higher-order modulation forward feeder link. The satellite can demodulate the higher-order modulator forward feeder link into a bit stream. This bit stream may then be remodulated and retransmitted as multiple forward user links.

Abstract: A system and method for beam switching by a User Terminal (UT). The method includes initiating a beam switch between an old beam and a new beam when the UT is disposed in an overlap area of the old beam and the new beam; duplicating over the new beam, at a Network Access Point (NAP), user traffic to the UT; and assigning a Time Division Multiplex Access (TDMA) allocation for the UT on the new beam, prior to an arrival of the UT on the new beam, where the user traffic traversing a satellite network remains uninterrupted during the beam switch and the NAP redirects user traffic for the UT via the old beam to the new beam.

Abstract: An apparatus and method for mitigating polarization mismatch in reflector antenna systems. A feed unit is configured to determine a polarization mismatch between a first polarization associated with a first wave and a second polarization associated with a reflector unit. The feed unit pre-distorts the first wave to achieve a compensated polarization for reducing and/or eliminating a polarization mismatch. The pre-distorted first wave having the compensated polarization is used to illuminate the reflector unit. A re-radiated wave is reflected by the reflector unit. Furthermore, the level of the re-radiated wave is increased as a result of the pre-distortion.
