  • Joint transmitter signal processing in multi-beam satellite systems
    Patent number: 10270520
    Abstract: A, method and apparatus for wirelessly transmitting data to a plurality of terminals in each of a plurality of beams through a plurality of transmit feeds includes selecting, for each beam, two or more terminals among the plurality of terminals in the beam as a subgroup of terminals, on the basis of channel state information of the plurality of terminals; determining, for each beam, equivalent channel state information representing the subgroup of terminals in the beam on the basis of the channel state information of the terminals of at least one of the plural subgroups of terminals; and determining a set of weight coefficients that relate the plurality of transmit feeds to a plurality of signals that are intended for transmission in the plurality of beams on the basis of the equivalent channel state information representing the plural subgroups of terminals.
