PARTICIPATING INSTITUTIONS: University of Alabama in HuntsvillePROJECT DESCRIPTION UltraWideband (UWB) is a radio technology that operates at a very low energy level for short-range, high-bandwidth communications using a large portion of the radio spectrum. The technology offers a solution to the future connectivity needs of the next -generation consumer electronic devices that cannot be met with today's wireless LAN and WPAN technologies. The attributes of high bandwidth, high fidelity, low power, low cost, and compact physical size which make UWB ideal for enabling wireless connectivity is also ideal for a hands-on instrumentation platform for learning the basic concepts in signals and signal processing for an electrical engineer. This project is enhancing undergraduate education in electrical engineering by incorporating recent advances in high performance UWB instrumentation into laboratories to improve student learning. This approach allows key fundamental concepts in signal and signal processing (e.g., the impulse response, modulation, time-domain/frequency-domain duality, sampling, signal orthogonality, correlations, and filtering) to emerge from mathematical theory using the UWB technology and materialize in hands-on experiments.The project is addressing the need to provide students unique hands-on practice with real-world technology to connect the dots between signal and signal processing concepts and system performance. Students crave these practical exercises so they can see the "big picture" and understand why learning these concepts is important. This laboratory fills a void in the curriculum that has been long overlooked. BROADER SIGNIFICANCE The project holds promise to bridge the gap between theoretical signal processing concepts and wireless operations via experiences in a practical laboratory environment. As future employee or graduate researchers, the students can immediately engage in the design process, an often-rare commodity. External feedback provided by industry is facilitating a line of communication, which is creating a better alignment of course content with current technology trends. Finally, the targeted materials developed during the project increase the likelihood of curriculum adoption by other institutions.

参与机构：亚拉巴马大学亨茨维尔分校项目描述超宽带（UWB）是一种无线电技术，它使用大部分无线电频谱，以非常低的能量水平进行短距离、高带宽通信。该技术为下一代消费电子设备的未来连接需求提供了解决方案，而这些需求无法通过当今的无线LAN和WPAN技术来满足。UWB具有高带宽、高保真度、低功耗、低成本和紧凑的物理尺寸等特性，是实现无线连接的理想选择，也是电气工程师学习信号和信号处理基本概念的实用仪器平台的理想选择。该项目通过将高性能UWB仪器的最新进展纳入实验室来提高学生的学习能力，从而加强电气工程的本科教育。这种方法允许信号和信号处理中的关键基本概念（例如，冲激响应、调制、时域/频域对偶、采样、信号正交性、相关性和滤波），从使用UWB技术的数学理论中浮现出来，并在动手实验中具体化。该项目旨在满足学生的需求，为学生提供独特的动手实践与现实世界的技术，将信号和信号处理概念与系统性能联系起来。学生渴望这些实践练习，这样他们就可以看到“大局”，并理解为什么学习这些概念是重要的。这个实验室填补了课程中一个长期被忽视的空白。更广泛的意义该项目有望通过实际实验室环境中的经验，弥合理论信号处理概念与无线操作之间的差距。作为未来的员工或研究生研究人员，学生可以立即参与设计过程，这是一种罕见的商品。工业界提供的外部反馈正在促进沟通渠道，使课程内容更好地符合当前的技术趋势。最后，在项目期间编制的有针对性的材料增加了其他机构采用课程的可能性。
