EARS: Spectrally Aware Interference Tolerant RF Nanosystems

频谱感知干扰容忍射频纳米系统PI：Dimitrios Peroulis，普渡大学摘要智力优势：该建议的首要目标是研究基于新的滤波架构和纳米机械谐振器的干扰抑制的基本问题。这些技术有望使纳米接收器具有传统接收器所没有的前所未有的能力。干扰抑制是自适应接收机可重构射频前端最关键的特征之一。与传统的简化方法不同，传统的简化方法通常根据噪声电平定义接收器的S最小可检测信号，而在信号密集的环境中，真正限制可实现通信范围的是信号干扰。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结构，即使在任意接近所需频段的情况下，也能够动态地抑制强干扰。2)展示了新的带阻滤波结构，这种结构可以用相对较低的品质因数集成谐振器实现，但只有在用高品质因数谐振器实现时才能达到传统滤波器中的抑制水平。3)展示用于目标1和目标2的集成纳米谐振器，该集成纳米谐振器基于简单的后CMOS工艺技术。集成的纳米谐振器将是高度可重复性、可调谐的，并将使用高成品率技术制造。广泛的影响：已经计划了一些步骤来扩大该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，广泛传播重要研究成果。具体地说，除了标准的期刊和会议出版物外，研究成果将被整合到微系统、射频设计和纳米工程的课程中。文章还将提交给通讯和微系统行业杂志，以便将工作传播给广大专业工程界。2)广泛使用MemsHUB门户网站，通过在线模拟工具向微/纳米工程界传播这项研究的结果。预计这将是弥合基础科学和微系统工程师之间差距的关键。3)通过NSF REU和/或其他资金来源支持本科生研究。所有教授都有让本科生参与他们研究的丰富历史。将雇用初级学生来支持这项拟议的研究。4)通过适当的项目吸引和留住美国少数族裔学生，并让本科生在职业生涯早期进行研究。通过普渡大学的服务学习和以项目为导向的项目来实现这些目标将是优先事项。调查人员在吸引和留住少数族裔学生方面已经有了记录，包括通过类似的努力。

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.
