具有节点间干扰的带内全双工空间自干扰抑制的自由度

Degrees of Freedom of Spatial Self-Interference Suppression for In-Band Full-Duplex with Inter-node Interference

Yujun Chen, Ashutosh Sabharwal

摘要:

我们研究了一个三节点网络,其中一个全双工基站与一个上行链路和一个下行链路半双工节点通信。在该网络中,存在自干扰和节点间干扰。我们使用基于天线理论的信道模型来研究这种网络的空间自由度,并研究空间隔离是否以及在多大程度上优于时分(即半双工)对应。使用自由度分析,我们表明,空间隔离优于时间分割,除非散射到预期用户的对象的角展重叠的对象,背散射到接收器的传播。

英文摘要:

We study a three-node network with a full-duplex base-station communicating with one uplink and one downlink half-duplex node. In this network, both self-interference and inter-node interference are present. We use an antenna-theory-based channel model to study the spatial degrees of freedom of such network, and study if and how much does spatial isolation outperforms time-division (i.e. half-duplex) counterpart. Using degrees of freedom analysis, we show that spatial isolation outperforms time division, unless the angular spread of the objects that scatters to the intended users is overlapped by the spread of objects that back scatters to the receivers.
