Spectrally Aware Interference Tolerant RF NanosystemsPI: Dimitrios Peroulis, Purdue UniversityAbstractIntellectual merit: The overarching goal of this proposal is to investigate fundamental issues of interference mitigation based on novel filtering architectures and nanomechancial resonators. These are expected to result in interference tolerant nanoreceivers with unprecedented capabilities not found in conventional receivers. Interference mitigation is among the most critical features of reconfigurable radio frequency front-ends of adaptive receivers. Unlike conventional simplified approaches that typically define a receiver?s minimum detectable signal with respect to its noise level, it is truly signal interference that primarily limits the achievable communication range in a signal-dense environment. As a result, the scientific objectives of this effort can be summarized as: 1) Investigate new adaptive filtering architectures with the ability to dynamically reject strong interferers even when located arbitrarily close to the desired band. 2) Demonstrate new bandstop filter architectures that can be implemented with relatively low quality factor integrated resonators but achieve rejection levels found in traditional filters only when implemented with high quality factor resonators. 3) Demonstrate integrated nanoresonators used for objectives 1 and 2 based on a simple post-CMOS processing technology. The integrated nanoresonators will be highly reproducible, tunable, and will be fabricated with high yield technologies.Broader Impacts: A number of steps have been planned to expand the broader impacts of this project. The most important activities include: 1) Integrate research results into the curricula and widely disseminate important research results. Specifically, in addition to standard journal and conference publications, research results will be integrated into the courses taught on microsystems, radio frequency design, and nanoscale engineering. Articles will also be submitted to communications and microsystems trade magazines to have the work spread to the professional engineering community at large. 2) Extensive use of the memsHUB web portal to disseminate results from this study to the micro/nano-engineering community through online simulation tools. This is expected to be critical in bridging the gap between fundamental science and microsystems engineers. 3) Support of undergraduate student research through the NSF REU and/or other funding sources. All professors have strong histories of involving undergraduates in their research. Junior-level students will be hired to support the proposed research. 4) Attract and retain U.S. minority students through appropriate programs as well as engage undergraduate students to research early in their careers. Accomplishing these goals through service-learning and project-oriented programs at Purdue will be a priority. The investigators have already a record in attracting and retaining minority students including through similar efforts.

频谱感知抗干扰RF NanosystemsPI：Dimitrios Peroulis，普渡大学摘要智力价值：该提案的首要目标是研究基于新型滤波架构和纳米机械谐振器的干扰缓解的基本问题。预计这些将导致具有传统接收器中没有的前所未有的能力的抗干扰纳米接收器。干扰抑制是自适应接收机的可重构射频前端的最关键特征之一。不同于传统的简化方法，通常定义一个接收器？的最小可检测信号相对于其噪声水平，它是真正的信号干扰，主要限制了可实现的通信范围在信号密集的环境。因此，这项工作的科学目标可以概括为：1）研究新的自适应滤波架构，即使在任意接近所需频带的情况下，也能够动态地拒绝强干扰。2)演示新的带阻滤波器架构，该架构可采用相对低品质因数的集成谐振器实现，但只有采用高品质因数谐振器实现时，才能达到传统滤波器的抑制水平。3)基于简单的CMOS后处理技术，演示用于目标1和2的集成纳米谐振器。集成的纳米谐振器将是高度可重复的，可调谐的，并将与高产量technology.Broader影响制造：一系列的步骤已经计划扩大这个项目的更广泛的影响。最重要的活动包括：1）将研究成果纳入课程，并广泛传播重要的研究成果。具体来说，除了标准的期刊和会议出版物，研究成果将被整合到微系统，射频设计和纳米工程教授的课程。文章也将提交给通信和微系统贸易杂志有工作传播到整个专业工程界。2)广泛使用memsHUB门户网站，通过在线模拟工具向微/纳米工程社区传播本研究结果。这对于弥合基础科学和微系统工程师之间的差距至关重要。3)通过NSF REU和/或其他资金来源支持本科生研究。所有的教授都有让本科生参与研究的悠久历史。大三学生将被雇用来支持拟议的研究。4)通过适当的项目吸引和留住美国少数民族学生，并让本科生在职业生涯的早期进行研究。通过普渡大学的服务学习和项目导向计划实现这些目标将是一个优先事项。调查人员在吸引和留住少数民族学生方面已经有了记录，包括通过类似的努力。
