具有交替连通性的拓扑干扰管理
Topological Interference Management with Alternating Connectivity
摘要：
拓扑干扰管理问题是指研究在网络拓扑之外的发射机处没有信道状态信息（没有CSIT）的部分连接的线性（有线和无线）通信网络的容量，即，知道哪些信道系数为零（比无线情况下的噪声本底弱）。虽然这个问题最初是用固定的拓扑结构来研究的，但在这项工作中，我们通过一系列简单的和概念上有代表性的例子来探索不同连接性的影响。具体来说，我们强调了在交替拓扑结构中编码的协同效益。
英文摘要：
The topological interference management problem refers to the study of the capacity of partially connected linear (wired and wireless) communication networks with no channel state information at the transmitters (no CSIT) beyond the network topology, i.e., a knowledge of which channel coefficients are zero (weaker than the noise floor in the wireless case). While the problem is originally studied with fixed topology, in this work we explore the implications of varying connectivity, through a series of simple and conceptually representative examples. Specifically, we highlight the synergistic benefits of coding across alternating topologies.
