综合系统方案的重点是开发技术来最小化相位噪声的影响，相位噪声是限制许多通信系统性能的主要因素之一。与现有的许多克服相位噪声的方法不同，我们建议结合信号处理技术和电路技术来克服相位噪声问题。基于这种综合方法，提出了一种具有潜在显著性能改进的新的相位噪声补偿方案。这项研究将证明所提出的相位噪声补偿方案在通信收发信机中的有效性。除了在清楚地了解各种设计选项以及相应的性能和实现复杂性的折衷的基础上提供完整的设计框架外，还将通过在硅上实现该方法来展示所提出的方法的可行性和优势。拟议研究中提出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(发射机和接收机)。上述研究计划与教育计划相结合，描述了拟议的研究将如何帮助培养研究生和本科生。拟议研究的多学科性质将扩大学生的技术理解，PI认为这是下一代工程师的必修课。该提案还包括改善代表性不足群体的参与程度的计划。最后，拟议的研究结果预计将使需要廉价和低功率通信设备的众多技术部门受益。

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.
