  • 摘要: 無線帶內(nèi)全雙工(IBFD)具有頻譜效率倍增潛力,應(yīng)用到多用戶接入時,共享信道的優(yōu)化分配將決定系統(tǒng)容量的實際增益。該文分析多用戶爭用沖突的干擾特性及鏈路分配的約束條件,以容量最大為優(yōu)化目標(biāo),針對雙向全雙工(BFD)、全雙工中繼(FDR)以及兩者混合的傳輸模式,建立信道資源分配的問題模型。通過典型站點分布的最優(yōu)解計算,分析IBFD系統(tǒng)相對半雙工(HD)的容量增益。結(jié)果表明,BFD有理想的100%增益,而FDR有較大變化范圍(最低增益25%)。此外,計算發(fā)現(xiàn),站點間傳輸鏈路呈現(xiàn)1維鏈型結(jié)構(gòu)的容量增益明顯優(yōu)于2維平面分布的鏈路結(jié)構(gòu)。
