在本文中，我们研究的中继干扰无线网络中，中继（助手）节点是为了促进竞争的信息流在无线网络中。我们研究这一点的背景下，确定性的无线交互模型，消除了信道噪声，并专注于信号的相互作用。利用这个模型，我们表明，几乎所有的已知方案，如干扰抑制，干扰对齐和干扰分离是必要的中继干扰网络。此外，我们发现了一种新的干扰管理技术，我们称之为干扰中和，它允许在空中干扰去除，而没有发射机完全访问干扰信号。我们表明，干扰分离，抑制和中和出现在一个基本的方式，因为我们表现出完整的特征的继电器干扰网络的特殊配置。
In this paper we study the relay-interference wireless network, in which relay (helper) nodes are to facilitate competing information flows over a wireless network. We examine this in the context of a deterministic wireless interaction model, which eliminates the channel noise and focuses on the signal interactions. Using this model, we show that almost all the known schemes such as interference suppression, interference alignment and interference separation are necessary for relay-interference networks. In addition, we discover a new interference management technique, which we call interference neutralization, which allows for over-the-air interference removal, without the transmitters having complete access the interfering signals. We show that interference separation, suppression, and neutralization arise in a fundamental manner, since we show complete characterizations for special configurations of the relay-interference network.
