Technical Summary: The main technical goal of this research is to solve the problem of index coding from an interference alignment perspective. The index coding problem lies at the intersection of several challenging problems in network information theory such as broadcast channels, source coding and network coding. This project explores the index coding problem and its generalizations as they relate to the problem of optimal interference management in wireless and wired communication networks, when only a coarse knowledge of network topology is available to the transmitters. Broader Significance:Understanding the capacity limits of wireless and wired networks under practical assumptions is critical for industry, academia, government agencies and society in general, to have realistic expectations from communication networks of the future. Interference between concurrent information flows is a key bottleneck in both wired and wireless networks. The unified perspective of interference management taken in this research allows existing insights to be translated from wireless networks to wired networks and vice versa, as well as the discovery of new insights that cut across applications. The research brings together areas like wireless communications, network coding, classical information theory, graph-theory, as well as optimization and algorithms, providing cutting-edge training to the participating student researchers in these critical technical areas.

技术总结：本研究的主要技术目标是从干扰对齐的角度解决索引编码的问题。索引编码问题是广播信道、信源编码和网络编码等网络信息理论中几个具有挑战性问题的交叉点。这个项目探讨了索引编码问题及其推广，因为它们涉及到无线和有线通信网络中的最佳干扰管理问题，当只有一个粗略的网络拓扑知识可供发射机。更广泛的意义：了解无线和有线网络在实际假设下的容量限制对于工业界、学术界、政府机构和整个社会来说至关重要，以便对未来的通信网络有现实的期望。并发信息流之间的干扰是有线和无线网络中的关键瓶颈。本研究中采用的干扰管理统一视角允许将现有见解从无线网络转换到有线网络，反之亦然，并发现跨应用的新见解。该研究汇集了无线通信，网络编码，经典信息论，图论以及优化和算法等领域，为参与这些关键技术领域的学生研究人员提供尖端培训。
