The integrative systems proposal focuses on developing techniques to minimize the effects of the phase noise, which is one of the primary factors that limit the performance in many communication systems. In contrast to many of the existing approaches for combating phase noise, we propose to use signal processing techniques together with circuit techniques to overcome the phase noise problems. Based on this integrated approach, a novel phase noise compensation scheme with potentially significant performance improvement is proposed. This research will demonstrate the effectiveness of the proposed phase noise compensation scheme in communication transceivers. In addition to providing a complete design framework based on a clear understanding of various design options and the corresponding tradeoffs in performance and implementation complexity, the feasibility and the advantages of the proposed approach will be demonstrated by realizing it on silicon. The concepts and techniques developed in the proposed research should be broadly applicable to all communication systems (transmitters and receivers) that suffer from the effects of phase noise. The above research plan is coupled with an education plan that describes how the proposed research will help train both the graduate and undergraduate students. The multi-disciplinary nature of the proposed research will broaden the students' technical understanding, which the PI believes is mandatory for next generation of engineers. The proposal also includes plans to improve the participation of underrepresented groups. Finally, the results of the proposed research are expected to benefit the numerous sectors of technology that require inexpensive and low-power communication devices.

集成系统的建议着重于开发技术以最大程度地减少相位噪声的影响，这是限制许多通信系统性能的主要因素之一。与许多现有的打击相位噪声的方法相反，我们建议将信号处理技术与电路技术一起使用以克服相位噪声问题。基于这种综合方法，提出了一种具有潜在显着性能改善的新型相噪声补偿方案。这项研究将证明拟议的相噪声补偿方案在通信收发器中的有效性。除了基于对各种设计选项的清晰了解以及性能和实施复杂性方面的相应权衡提供完整的设计框架外，还将通过在硅上实现拟议方法的可行性和优势。拟议的研究中开发的概念和技术应广泛适用于遭受相位噪声影响的所有通信系统（发射器和接收器）。以上研究计划与一项教育计划相结合，该计划描述了拟议的研究将如何帮助培训研究生和本科生。拟议研究的多学科性质将扩大学生的技术理解，PI认为这对于下一代工程师来说是必须的。该提案还包括改善代表性不足的群体参与的计划。最后，预计拟议的研究的结果将使需要廉价且低功率的通信设备的技术领域受益。
