CAREER: Energy-Efficient Wireless Communications Under Channel Uncertainty: Fundamental Limits and Tradeoffs

拟议活动的知识价值。该研究具有创新性和原创性，因为它解决了无线通信中的两个重要挑战，即能量效率和信道不确定性，并在能量效率是最终目标的情况下建立了重要的权衡。这些研究和教育活动的预期成果包括：理解在信道不确定性下工作对诸如信道容量等最终性能极限的影响;提出以基本带宽-功率权衡为基准的新型节能信令方案;理解协作和跨层设计对节能的影响;利用有吸引力的无线通信理念在本科生和研究生中创造学科的兴奋点，并利用这种兴奋点让学生通过积极参与研究来参与知识的进步。这个研究项目与教育的整合将通过修订和新引进的课程来完成，涉及PI研究计划的本科生，以及这些学校的推广。代表性不足的群体的参与将通过PI'seorts来实现，以招募女本科生和研究生，并在内布拉斯加州MESA方案中开展活动，该方案针对内布拉斯加州的少数民族和代表性不足的青年。将通过在高质量的同行评审期刊和国际会议上发表本研究项目的结果，并为PI的研究小组创建一个网站，来实现结果的广泛传播。研究成果将有助于提高无线系统在严重物理障碍下的可靠性和鲁棒性，最终实现泛在通信的无线愿景。特别是能量效率分析预计将对下一代无线网络的设计产生影响，包括在健康，军事和家庭中具有各种应用领域的传感器网络。沿着这些研究成果，社会也将受益于作为该项目教育计划一部分的外展计划。

Intellectual Merit of the Proposed Activity. The proposed research is creative and original because it addresses two important challenges in wireless communications, namely energy eciency and channel uncertainty, in combination and oers to establish the important tradeos when energy eciency is the ultimate goal. The expected outcomes of the proposed research and educational activities include an understanding of the impact upon the ultimate performance limits, such as channel capacity, of operating under channel uncertainty; proposals of novel energy ecient signaling schemes using the fundamental bandwidth-power tradeo as a benchmark; an understanding of the eect of cooperation and cross-layer designs on the energy-eciency; creation of excitement in the discipline among undergraduate and graduate students using the attractive wireless communication ideas and using this excitement to have the students participate in the advancement of knowledge by actively engaging in research.Broader Impacts. Integration of this research project with education will be accomplished throughrevised and newly introduced courses, involving undergraduates in the PI's research program, and thesecondary school outreach. The participation of underrepresented groups will be achieved by the PI'seorts to recruit female undergraduate and graduate students, and activities in the Nebraska MESAProgram, which target Nebraska's minority and underrepresented youth. Broad dissemination of resultswill be accomplished by publishing the results of this research project in high quality, peer-reviewedjournals and international conferences and creating a web site for the PI's research group. It is ex-pected that the outcomes of the research will improve wireless systems to achieve ecient and robustperformance even under severe physical impediments, leading to the realization of the wireless visionof ubiquitous communications. Especially the energy eciency analysis is expected to have an impactupon the design of next generation wireless networks, including sensor networks that have various ap-plication areas in health, the military, and the home. Along with these research outcomes, society willalso benefit from the outreach programs proposed as part of the educational plan of the project.
