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.

拟议活动的智力价值。拟议的研究具有创造性和原创性，因为它解决了无线通信中的两个重要挑战，即能源效率和信道不确定性，并在能源效率为最终目标时建立了重要的权衡。拟议研究和教育活动的预期成果包括了解在渠道不确定性下运行对最终性能限制（例如渠道容量）的影响；使用基本带宽功率权衡作为基准的新型节能信号传输方案的提案；了解合作和跨层设计对能源效率的影响；使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兴奋感，并利用这种兴奋让学生通过积极参与研究来参与知识的进步。更广泛的影响。该研究项目与教育的整合将通过修订和新引入的课程来实现，让本科生参与 PI 的研究计划，并扩大中学范围。代表性不足的群体的参与将通过 PI 招收女本科生和研究生的工作以及针对内布拉斯加州少数民族和代表性不足的青年的内布拉斯加州 MESA 计划的活动来实现。通过在高质量、同行评审的期刊和国际会议上发表该研究项目的结果，并为 PI 研究小组创建一个网站，可以实现成果的广泛传播。预计该研究成果将改善无线系统，即使在严重的物理障碍下也能实现高效、鲁棒的性能，从而实现无处不在的通信的无线愿景。特别是能源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、军事和家庭等各种应用领域的传感器网络。除了这些研究成果之外，社会还将受益于作为该项目教育计划一部分提出的外展计划。
