天線陣列方位對(duì)MIMO無(wú)線信道性能的影響

Impact of Antenna Array Orientation on Performance of MIMO Wireless Channels

  • 摘要: 分析收發(fā)天線陣列的方位對(duì)MIMO無(wú)線信道的空域相關(guān)性及其容量的影響,得出在散射信號(hào)角度擴(kuò)展較小時(shí),這種影響不容忽視,為得到更大的信道容量,應(yīng)使陣列法線盡可能指向來(lái)波/去波平均方向.數(shù)值結(jié)果證實(shí)了天線陣列方位對(duì)相關(guān)系數(shù)的影響,并指出這種影響隨天線陣列法線偏離其信號(hào)平均方向而增大.仿真結(jié)果表明信號(hào)角度擴(kuò)展較小的陣列的方位對(duì)信道容量影響更大,增大信號(hào)角度擴(kuò)展可以削弱以至消除這種影響.
