论文摘要
流体天线代表了一个概念，其中机械柔性天线可以在给定空间内自由切换其位置。最近，据报道，即使有一个很小的空间，单恒纳液体天线系统（FAS）也可以按照中断的概率（或端口）的数量（或端口）切换到l-antenna最大比率组合（MRC）组合（MRC）组合系统，就足够大。这封信旨在研究FAS是否也可以通过较小的空间来实现非凡的能力。我们通过得出千古能力和下限能力来做到这一点。该字母还得出了FAS的水平交叉率（LCR）和平均淡出持续时间（AFD）。
Fluid antenna represents a concept where a mechanically flexible antenna can switch its location freely within a given space. Recently, it has been reported that even with a tiny space, a single-antenna fluid antenna system (FAS) can outperform an L-antenna maximum ratio combining (MRC) system in terms of outage probability if the number of locations (or ports) the fluid antenna can be switched to, is large enough. This letter aims to study if extraordinary capacity can also be achieved by FAS with a small space. We do this by deriving the ergodic capacity, and a capacity lower bound. This letter also derives the level crossing rate (LCR) and average fade duration (AFD) for the FAS.
