英文摘要	Multibeam satellite systems have the potential to substantially increase the capacity of the whole system. In this paper, we study the criteria in multibeam satellite downlinks weighting vector design and propose a now tradeoff power allocation algorithm. Traditional algorithms, such as maximum capacity and proportional fairness, can not make a compromise between total capacity maximization and uses' fairness. The now algorithm, which we call 'tradeoff allocation', is based on maximum capacity algorithm, and simply changes its cost function to provide a sensible compromise between total capacity maximization and fairness. Compared with other compromise algorithm, tradeoff allocation algorithm is simpler and more flexible, because the different choose of parameter can provide different allocation. In addition, we also propose priority allocation strategy and it can optimize traditional allocation algorithm and make the power allocation more reasonable in special practical application.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000262975200027&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Engineering, Electrical & Electronic; SCI(E); EI; 0; ARTICLE; 1; 137-140; 18
