一种卫星多波束中的波束选择构架及实现方法
A Beam-selecting Framework and Implementation Method Based on Multi-beam Satellite
摘要
Abstract
An onboard beam-selecting framework and corresponding implementation method for multi-beam satellite communication is proposed to provide high gain links for widely distributed users with small quantity of payloads. The framework is composed of beam grouping module and beam selecting module. During the process of implementation,the frequency response of multi-filter is used. For both uplink and downlink,by controlling the output of local oscillators,each beam can supply service to users located in any spot area . By periodically altering the direction of each beam,the high gain communication links in wide area can be supplied by small number of transponders. By comparison with the satellite configuring the same number of beams,analysis shows that the proposed framework can reduce the power consumption and the weight of payload substantially. By comparison with the satellite configuring the same payload weight and power consumption,the result shows that the proposed framework can increase the transmission per-formance of each beams and the throughput of satellite essentially.关键词
