This EARS (Enhancing Access to the Radio Spectrum) program was founded in response to the 2010 Presidential Memorandum on Unleashing the Wireless Broadband Revolution mandated by Congress as part of the National Broadband Plan. It was referenced in 2010 State of the Union and later on the Middle Class Tax Relief and Job Creation Act of 2012 (More than 1/3 of the bill deals with radio spectrum), the PCAST 2012 Report [President's Council of Advisors on Science and Technology] (which calls for vastly increased use of spectrum sharing) and the 2013 Presidential memo (Expanding America's Leadership in Wireless Innovation). The aim of this program is to identify bold new concepts with the potential to contribute to significant improvements in the efficiency of radio spectrum utilization, protection of passive sensing services, and in the ability for traditionally underserved Americans to benefit from current and future wireless-enabled goods and services. The impact is large on the economics of the Nation as seen on the last FCC bidding of 65MHz of the spectrum for over $45 billion early in 2015. It will enable access to science, engineering, industry, civilian and military users of the RF spectrum.Effective use of radio spectrum is coveted by both active services (e.g., cellular, radar, wireless internet) and passive services (e.g., radio astronomy service (RAS) and earth exploration satellite service (EESS)). It has led to an increasing tension between the growing demand for greater spectrum use by active radios and the pressing need for quiet spectrum by passive systems. The first and foremost step towards alleviating this tension is to monitor the radio frequency environment at high resolution in time, space, frequency, and even some appropriately defined feature space. Although the spectrum monitoring issue has undergone extensive research and radio frequency interference (RFI) detection has been fervently investigated in the remote sensing communities, only limited efforts exist in examining spectrum monitoring from the perspectives of both active and passive systems to conscientiously support coexistence. To support peaceful coexistence on radio spectrum, this project aims to develop efficient spectrum monitoring techniques that provide deep understanding and technological enablers for future spectrum management in the growing presence of active and passive radio services. Advanced signal processing techniques will be developed to provide high-resolution spectrum sensing at short sensing time, and optimal sensing resource allocation schemes will be investigated to maximize the payoffs of the sensing budget. The proposed research on spectrum sensing will inform and advance the RFI detection and management in support of increased societal and scientific returns from RAS and EESS investments. The developed techniques can also be leveraged by cognitive radio networks for dynamic spectrum sharing, impacting practices of the services like cellular data and Internet of things (IoT). Graduate and undergraduate students will benefit from the unique interdisciplinary nature of this research, especially through interactions with the scientists at the Arecibo Observatory, and the hands-on experience with its 305 m telescope.

该耳朵（增强无线电频谱的访问）计划是根据2010年总统备忘录释放国会作为国家宽带计划的一部分的无线宽带革命的响应而建立的。它在2010年国际电联的2012年中产阶级税收减免和创造就业法案（超过1/3涉及无线电频谱），PCast 2012 2012报告[总统科学技术顾问委员会]（呼吁大大增加频谱共享的使用）和2013年美国总统纪念馆（扩大无线领导力的领导力）。该计划的目的是确定大胆的新概念，有可能为无线电频谱利用率的效率，被动传感服务的保护以及传统上服务不足的美国人从当前和未来的无线支持商品和服务中受益的能力做出重大改善。在2015年初的65MHz频谱的最后一次FCC竞标中所见，对国家经济的影响很大。它将在RF Spectrum的RF Spectrum的科学，工程，工业，工业，平民和军事用户中访问无线电频谱的有效使用。无线电频谱的使用（例如，无线电，cellect，e.G.无线电，无线电）（例如，无线电），无线电（E.G.） （RAS）和地球勘探卫星服务（EESS）。这导致了不断增长的主动收音机对更大频谱使用的需求与被动系统对安静频谱的紧迫需求之间的紧张关系。减轻这种张力的第一和第一个步骤是在时间，空间，频率甚至某些适当定义的特征空间中监视射频环境。尽管频谱监测问题已经进行了广泛的研究和射频干扰（RFI）检测，但在遥感社区中进行了热烈的研究，但从主动和被动系统的角度检查频谱监测时，仅存在有限的努力，以认真地支持支持共存。为了支持广播频谱上的和平共存，该项目旨在开发有效的频谱监测技术，从而为未来的积极和被动无线电服务的存在提供深刻的理解和技术促进器。将开发先进的信号处理技术，以在短传感时提供高分辨率频谱感应，并将研究最佳的感应资源分配方案，以最大程度地提高传感预算的回报。拟议的有关频谱感知的研究将为RFI检测和管理提供信息，以支持RAS和EESS投资的社会和科学回报增加。认知无线网络也可以利用开发的技术来利用动态频谱共享，从而影响诸如蜂窝数据和物联网（IoT）等服务的实践。研究生和本科生将受益于这项研究的独特跨学科性质，尤其是通过与Arecibo天文台的科学家的互动以及其305 M望远镜的动手体验。
