摘要： A system and method for communicating information from a base station to one or more user terminals via a forward link to a relay and distribution device is provided. The method includes determining a separate information rate for information to be transmitted from the base station to each of the user terminals. Each information rate is determined to allow successful communication with the respective user terminal and to provide a predetermined amount of link margin above a threshold energy-to-noise ratio (Eb/No) in the forward link. The method additionally includes formatting data received at the base station into a continuous time division multiplexed (TDM) data stream that includes a plurality of data frames to be transmitted to the user terminals. Each data frame is formatted to have the determined information rate of the respective user terminal destine to receive the data frame. The TDM data stream is transmitted using a single carrier of the forward link. Furthermore, the method includes continuously and dynamically adjusting the information rate of subsequent data frames for each user terminal to maintain successful communication and maintain the predetermined amount of margin as operating conditions of each user terminal change.

摘要： An apparatus and method for correcting antenna beam misalignment between a transmit antenna and a receive antenna on a mobile platform such as an aircraft. The beam alignment method makes use of sequential lobing to determine the pointing angles in azimuth and elevation of a receive beam received by the receive antenna. For the transmit antenna, sequential lobing is used for the transmit antenna beam transmitted to a transponded satellite and then to a ground station. The ground station performs received signal strength indicator (RSSI) measurements and transmits these measurements back to the aircraft 16 via the target satellite. From these measurements, the beam misalignment between the receive and transmit antenna beams, both in azimuth and elevation, can be determined and a correction applied to the transmit antenna. The beam alignment procedure of the present invention can be implemented without interfering with normal use of the transmit and receive antennas and further ensures that interference with satellites adjacent to the target satellite will not occur during return link transmissions from the aircraft to the ground station.
