超低功耗无线网络的抗畸变通信[j]：吴敬贤，方案No. 1202075摘要智能优点：超低功耗是下一代无线传感系统面临的最艰巨的挑战之一，下一代无线传感系统有望在极有限的电池容量或小型能量清除装置下连续运行数年或数十年。本研究项目的目标是通过一种新的抗失真通信范式来推进超低功耗无线网络的知识，这种通信范式故意允许系统中的可控失真。如果我们接受失真在实际通信系统中是不可避免的这一事实，为什么不直接设计一个对失真具有天然容忍度的系统呢？允许而不是最小化失真，所提出的容忍失真通信可以在超过香农信道容量限制的速率区域内运行，这是无失真通信的最终限制，从而实现传统技术无法比拟的显著功耗降低。研究方法是系统构建超低功耗容畸变无线网络的理论、设计工具、使能技术和原型，用于长期结构健康监测、生物医学传感等无线监测系统。容错通信设计方法与当前通信研究中占主导地位的错误最小化、吞吐量最大化和/或延迟最小化设计标准完全不同。新的理论和技术是利用无线监控系统的独特特点，如延迟容忍、畸变容忍、低数据速率和空间数据相关性，为网络设计提供了额外的自由度。抗畸变通信将使创新的理论和技术能够应对超低功耗通信带来的独特挑战和机遇。更广泛的影响：拟议的研究和教育活动的结果将加速超低功耗无线网络的广泛部署，用于环境和结构监测、监视和生物医学传感，可以提供早期预警，防止灾难性后果，改善公共安全和国土安全，促进公众的健康和福祉。推广活动，如每年访问高中和少数民族机构进行互动项目演示，将吸引更多代表性不足的学生追求科学和工程方面的职业道路。

Distortion-Tolerant Communication for Ultra-Low Power Wireless NetworksPI: Jingxian Wu, Proposal No. 1202075AbstractIntellectual Merit: Ultra-low power consumption is one of the most formidable challenges faced by the next generation wireless sensing systems, which are expected to operate uninterrupted over years or decades under extremely limited battery capacity or small energy scavenging devices. The goal of this research project is to advance the knowledge of ultra-low power wireless networks with a new paradigm of distortion-tolerant communication, which deliberately allows controlled distortion in a system. If we accept the fact that distortion is inevitable in practical communication systems, why not directly design a system that is naturally tolerant to distortion? Allowing instead of minimizing distortion, the proposed distortion-tolerant communication can operate in rate regions beyond the constraints imposed by Shannon channel capacity, the ultimate limit of distortion-free communications, thus achieving significant power reduction unrivaled by conventional technologies. The research approach is to systematically construct the theories, design tools, enabling technologies, and prototypes of ultra-low power distortion-tolerant wireless networks, which can be used for applications such as long-term structure health monitoring, biomedical sensing, and other wireless monitoring systems. The distortion-tolerant communication design approach is radically different from the error-minimization, throughput-maximization, and/or latency-minimization design criteria that dominate the current communication research. The new theories and technologies are developed by exploiting the unique features of wireless monitoring systems, such as delay-tolerance, distortion-tolerance, low data rate, and spatial data correlation, which provide extra degrees of freedom in the network design. The distortion-tolerant communication will enable innovative theories and technologies that are capable of coping with the unique challenges and opportunities arising from ultra-low power communications. Broader Impacts: The outcomes of the proposed research and education activities will accelerate the wide range deployment of ultra-low power wireless networks for environmental and structure monitoring, surveillance, and biomedical sensing, which can provide early warning to prevent catastrophic results, improve public safety and homeland security, and promote the health and well-being of the general public. Outreach activities, such as annual visits to high schools and minority institutions for interactive project demonstrations, will attract more underrepresented students to pursue a career path in science and engineering.
