Abstract0916713 - CIF: Small: Structured Transmission Strategies for Wireless NetworksIn this project, we use lattice and other structured coding techniques to induce alignment in wireless networks. This effort uses these codes on three different fronts: a.) Interference networks, where we use structured codes to align the interference seen at each receiver. The objective is to determine the capacity of this channel to within a constant gap using these codes. b.) Cognitive networks - where we use lattice codes to mitigate the interference seen by both the licensed and the cognitive radios. We exploit code structure to both (partially) learn the interfering signal at the cognitive radio and then use this knowledge to precode/align our interference signal. c.) Secure wireless networks: again, we utilize the structure of the codebook to determine simple transformations at the source in order to keep eavesdroppers in the network at bay. We employ these codes to detect, and depending on code structure, correct for modification attacks on the codebook.

Abstract0916713 - CIF：小型：无线网络的结构化传输策略在这个项目中，我们使用点阵和其他结构化编码技术来诱导无线网络中的对齐。这项工作在三个不同的方面使用这些代码：a.) 干扰网络，我们使用结构化代码来调整每个接收器处看到的干扰。目的是使用这些代码确定该通道在恒定间隙内的容量。 b.) 认知网络 - 我们使用点阵码来减轻许可无线电和认知无线电所受到的干扰。我们利用代码结构（部分）学习认知无线电中的干扰信号，然后使用这些知识来预编码/对齐我们的干扰信号。 c.) 安全无线网络：我们再次利用密码本的结构来确定源头的简单转换，以防止网络中的窃听者。我们使用这些代码来检测并根据代码结构来纠正对码本的修改攻击。
