The objective of this research is to formulate theories and techniques for a new communication paradigm of cooperative detection. This approach leverages cooperation among destination nodes during detection. The approach is to utilize the fact that wireless signals intended for one node are also overheard by neighboring nodes, thus a cluster of adjacent nodes can cooperatively recover the original information by exploiting spatial signal correlation through game theoretic information sharing and distributed source-channel coding.With respect to intellectual merit, this work seeks to increase network throughput and reliability through the use of cooperative detection. Existing research on cooperative communication is dominated by a focus on cooperative transmission, which relies on coordination among transmitters to achieve specific signal structure at receivers. Cooperative detection, as investigated in this project, instead exploits the intrinsic signal correlation among neighboring receivers without requiring explicit coordination among transmitters. It enables a family of communication techniques that have the potential to be inherently robust against the lack of precise coordination and to fully exploit the spatial diversity inherent in wireless networks.With respect to broader impact, this research has the potential to close the gap between theoretical network capacity and practical achievable throughput and to accelerate the deployment of high data rate reliable wireless networks to a variety of operational scenarios. The project provides research experiences for undergraduate students and interactive demonstrations to students from underrepresented groups during department open house and site visits to minority serving institutions.

本研究的目的是为协作检测的新通信范式制定理论和技术。 这种方法在检测过程中利用了目标节点之间的合作。 该方法是利用一个事实，即发送给一个节点的无线信号也会被相邻节点监听，因此一组相邻节点可以通过博弈论信息共享和分布式源信道编码来利用空间信号相关性来协作恢复原始信息。在智力方面，这项工作旨在通过使用协作检测来提高网络吞吐量和可靠性。 现有的协作通信研究主要集中在协作传输上，协作传输依赖于发射机之间的协调来在接收机处实现特定的信号结构。 正如本项目所研究的，协作检测利用相邻接收器之间的固有信号相关性，而不需要发射器之间的显式协调。 它使一系列通信技术具有固有的鲁棒性，能够克服缺乏精确协调的问题，并充分利用无线网络固有的空间多样性。就更广泛的影响而言，这项研究有可能缩小理论网络容量和实际可实现吞吐量之间的差距，并加速高数据速率可靠无线网络在各种操作场景中的部署。 该项目为本科生提供研究经验，并在部门开放日和对少数族裔服务机构的实地考察期间向来自代表性不足群体的学生提供互动演示。
