天線陣結構對非視距室內MIMO信道容量的影響

Antenna Array Structures Effect on Capacity of Indoor NLOS MIMO Channel

  • 摘要: 采用2維射線跟蹤法分析了非視距室內環(huán)境中天線間隔、天線陣形對MIMO系統(tǒng)容量和互補累積分布函數(CCDF)的影響。結果表明隨著天線間隔減小,MIMO系統(tǒng)容量降低。10%中斷容量表明,天線間隔相同時,有獨立同分布瑞利信道容量大于線性陣容量大于方陣容量或者圓形陣容量的關系。當天線間隔大于等于3 時,不同天線陣列陣形對容量影響非常小,此時i.i.d.瑞利信道理論容量幾乎全部實現。當天線間隔小于等于1 時,天線陣列陣形對容量影響較大,矩形陣和圓形陣MIMO系統(tǒng)容量相差較小,但都顯著小于線性陣列系統(tǒng)容量。在非視距的室內環(huán)境中,要實現最大的MIMO容量增益,設計天線陣列時應該對天線間隔和陣列陣形綜合考慮。
