資源簡介
計算最佳多用戶發射波束成形很困難,但該解決方案具有簡單直觀的結構,每個用戶只有一個設計參數。這一基本屬性使許多研究人員能夠提出啟發式波束形成方案 - 這里有許多基本相同的簡單方案的名稱。最佳波束成形使得在低SNR下的接收信號功率最大化,最小化高SNR下的干擾泄漏,以及在中間SNR處的這些沖突目標之間的平衡。
最佳波束形成結構可以擴展到實際的多小區場景,如本講座中簡要描述的那樣?;诒镜匦诺罓顟B信息(CSI)或收發器硬件損傷的備選波束成形參數化可以在[7]中找到。該領域中的一些開放問題是對不完美CSI的魯棒性,對多天線用戶的多流波束成形,其中每個信號用于一組用戶的多播,以及基于效用函數的自適應參
