  • Beamforming technique for broadband satellite communications
    Patent number: 8310980
    Abstract: Method for assigning a precoding beam forming scheme in a broadband satellite system, wherein said broadband satellite system comprises a multibeam satellite (1) having a plurality of antennas and a plurality of satellite beams, a gateway (2) and a number N of satellite terminals (ST11, ST12 . . . ST21, ST22, ST23 . . . STK1, STK2 . . . ), and wherein said gateway (2) is configured for processing and serving a plurality of K beams of said plurality of satellite beams towards said number N of satellite terminals (ST11, ST12 . . . ST21, ST22, ST23 . . . STK1, STK2 . . . ), wherein K<N, and wherein said assignation of a precoding beam forming scheme comprises a joint processing over said plurality of K beams. Said precoding beam forming scheme is dependent: on the radiation pattern of said satellite antennas; on the line of sight channel characteristics and on the multiuser diversity caused by said number N of satellite terminals (ST11, ST12 . . . ST21, ST22, ST23 . . . STK1, STK2 . . . ).
