| Abstract: | A preliminary discussion on space-ground integrated beamforming technology in hybrid satellite- terrestrial communication system is made. The importance of this technology is shown. Two realization archi- tectures iricluding the ground-based beamforming and the hybrid on space/on ground beamforming are ana- lyzed. Some key techniques such as uplink and downlink adaptive beanaforming algorithm,feeder link transmis- sion multiplex and remote errors effect calibration are discussed. |
