Energy-efficient Resource Allocation Based on Multi-user Massive MIMO System

  • 摘要: 該文針對(duì)多用戶大規(guī)模多輸入多輸出(MIMO)移動(dòng)通信上行系統(tǒng),提出一種基于能效優(yōu)化的資源分配算法。所提方法在采用最大比合并(MRC)接收情況下,滿足用戶數(shù)據(jù)速率和可容忍的干擾水平約束條件下,以最大化系統(tǒng)能效下界為準(zhǔn)則建立優(yōu)化模型。根據(jù)分?jǐn)?shù)規(guī)劃的性質(zhì),把原始的分?jǐn)?shù)最優(yōu)化問題轉(zhuǎn)換成減式的形式,進(jìn)而采用凸優(yōu)化的方法,通過聯(lián)合調(diào)整基站端的發(fā)射天線數(shù)和用戶的發(fā)射功率來優(yōu)化能效函數(shù)。仿真結(jié)果表明,所提算法與窮舉算法在能效上的差距不足9%,并且有較好的系統(tǒng)頻譜效率性能,同時(shí)算法復(fù)雜度得到了顯著降低。
