【摘要】：為了提高蜂窩式衛(wèi)星移動(dòng)通信的通信質(zhì)量和頻譜使用效率,必須對(duì)各波束載波頻率的選取進(jìn)行合理規(guī)劃.為此,將頻譜資源動(dòng)態(tài)規(guī)劃問題形式化,提出一種基于遺傳算法和啟發(fā)式搜索的頻譜動(dòng)態(tài)規(guī)劃算法,綜合考慮同頻復(fù)用距離、波束分組類約束、動(dòng)態(tài)變化的可用頻譜資源、用戶業(yè)務(wù)頻譜需求等,動(dòng)態(tài)地將可用頻譜資源分配至各波束,以最大效用地利用衛(wèi)星頻譜資源.
[Abstract]:In order to improve the communication quality and spectrum efficiency of cellular satellite mobile communication, it is necessary to plan the carrier frequency of each beam reasonably. In this paper, a spectrum dynamic programming algorithm based on genetic algorithm and heuristic search is proposed to formalize the problem of spectrum resource dynamic planning, which considers the frequency multiplexing distance, the constraint of beam grouping class and the dynamic change of available spectrum resources. The available spectrum resources are dynamically allocated to each beam to maximize the utility of satellite spectrum resources.
