CSR: Medium: Collaborative Research: Embedded System Design Optimization and Adaptation using Compact System-Level Models

该项目将开发新技术，以帮助先进的信号处理计算系统更好地适应其运行环境。这个项目很重要，因为信号处理无处不在（手机，计算机网络，制造系统，农业等）。适应环境有助于这些系统更可靠地运行，例如，适应不断变化的无线电干扰或高层建筑群带来的挑战性无线电环境。这些通信系统中的许多也是电池供电的，或者必须在有限的能量下运行;适应其操作环境有助于降低其能耗并延长电池寿命。这些技术对认知无线电特别有用，认知无线电是一种新兴技术，可以让无线通信设备（如手机）更有效地使用无线电频谱。本项目将开发新的方法来创建可在运行时重新配置的软件。典型的软件是为了在特定模式下运行而创建的;改变软件的运行条件需要重新设计软件本身。新的数学模型和算法将允许系统设计者创建软件，使其能够动态地适应环境。该项目将解决指定软件行为的两个模型，并将该规范转换为有效的实现。主要研究人员将与法国雷恩国家科学院（INSA）和台湾新竹国立交通大学的同事合作。法国和台湾的合作者将提供认知无线电算法和硬件方面的专业知识，以补充主要研究人员在软件设计方面的专业知识。这项合作还将为参与该项目的学生研究助理提供宝贵的国际经验。认知无线电将被用作本科生和研究生课程中的一个驱动示例，将该项目的研究成果整合到教育中。PI将积极为该项目招募代表性不足的少数民族学生。

This project will develop new techniques to help advanced computing systems for signal processing better adapt to the environments in which they operate. This project is important because signal processing is everywhere (cell phones, computer networks, manufacturing systems, agriculture, etc.). Adapting to the environment helps these systems to operate more reliably by, for example, adapting to changing radio interference or the challenging radio environments presented by clusters of tall buildings. Many of these communication systems are also battery-operated or must run on limited energy; adapting to their operating environments helps to reduce their energy consumption and improve battery life. These techniques are particularly useful for cognitive radio, an emerging technology that allows devices for wireless communication (such as cell phones) to more efficiently use radio spectrum.This project will develop new methods for creating software that can be reconfigured at run time. Typical software is created to operate in a particular mode; changing the software's operating conditions requires redesigning the software itself. New mathematical models and algorithms will allow system designers to create software that is designed to adapt itself dynamically to its environment. The project will address both models specifying the behavior of the software and for translating that specification into an efficient implementation.The principal investigators will collaborate with colleagues at the Institut National des Sciences Appliquées (INSA) in Rennes, France, and National Chiao Tung University in Hsinchu, Taiwan. The collaborators in France and Taiwan will provide expertise in cognitive radio algorithms and hardware that complements the principal investigators' expertise in software design. The collaboration will also provide valuable international experience for the student research assistants involved in the project. Cognitive radio will be used as a driving example in coursework for undergraduate and graduate students to integrate research results from this project into education. The PIs will actively recruit underrepresented minority students for this project.
