本文介绍了实验特性的自干扰（SI）信道的带内全双工（IBFD）通信系统，采用波束控制，多可重构天线（MRA），无源SI抑制。首先，我们描述了一个全双工基站的系统模型，同时突出与每个信号分量相关联的信道损伤。给出了IBFD系统在5MHz、10MHz和20MHz带宽上测量的SI信道功率延迟曲线。我们比较了在静态和动态环境中导致视线抑制（和非抑制）的波束图案的测量结果。然后，我们统计模型的SI通道进行概率分布拟合SI通道数据，这是在动态环境中收集的，在高和低SI抑制条件下提供的MRA。最后，使用拟合优度检验对候选概率分布模型进行比较。
This paper presents experimental characterization of the self-interference (SI) channel for In-Band Full-Duplex (IBFD) communication systems that employ beam steering, Multi reconfigurable antennas (MRA), for passive SI suppression. First, we describe a system model of a full-duplex base station while highlighting channel impairments associated with each signal component. We present the SI channel power delay profiles measured by IBFD system operating on 5MHz, 10MHz and 20MHz bandwidths. We compare the measurements for beam patterns that result in line of sight suppression (and non-suppression) in both static and dynamic environments. We then statistically model the SI channel by performing probability distribution fitting to SI channel data, which is collected in dynamic environment, under high and low SI suppression conditions provided by MRA. Finally, candidate probability distribution models are compared using goodness of fit test.
