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 radio frequency (RF) spectrum.Active wireless systems (which transmit and receive RF signals) such as cellular wireless communications have generated numerous advancements in our society and tremendous impacts on the national economy. Passive wireless systems (which only receive usually very faint signals) such as radio astronomy and earth exploration remote sensing have provided economically and scientifically important observations of Earth's environment, our solar system and the cosmos (e.g., weather forecasting, observation of solar flares which could affect infrastructure and lives on Earth). Both types of systems play crucial roles for the growth of humanity, thus their advancements need to be accommodated. However, their spectrum requirements are growing and conflicting to a large degree, and radio frequency interference (RFI) from active systems to passive systems is an increasing concern. This calls for a new paradigm of spectrum access and sharing that can cope with the future's needs. This project proposes such a paradigm between cellular wireless communications (CWC) and radio astronomy systems (RAS). The project develops a novel time and frequency division spectrum access between CWC and RAS, which not only resolves the spectrum requirement conflict but also enhances spectrum access opportunities for both systems. Instead of relying on the geographical isolation of RAS telescopes to avoid RFI, the project introduces a geographical coexistence paradigm between CWC and RAS through the use of a large number of distributed auxiliary radio telescopes (DARTs). The very large scale DARTs will suppress the RFI issue and potentially enable a quantum leap in RAS's capabilities. In addition, the project develops novel adaptive circuitry and signal processing algorithms to handle the RFI issue efficiently. In brief, this project develops an interdisciplinary and mutually-beneficial technical solution and framework for spectrum access of CWC and RAS through coordination between them. CWC could gain more spectrum access opportunities which will enable more wireless services/applications and new business opportunities, thus expanding and enriching the national economy. RAS will secure more spectrum access opportunities and enhanced astronomical observation capabilities, thus accelerating its contributions to the fundamental science, knowledge of the universe, and protection of lives on Earth through space environmental information.

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。这种影响对国家经济的影响很大，如2015年初的65MHz频谱的最后一次FCC竞标中，其影响超过450亿美元。它将能够进入科学，工程，工程，工业，工业，工业，平民和军事用户（RF）Spectrum Spectrum.Active无线系统（如众所周知）的无线沟通以及在我们的无线沟通中的多种沟通，并获得了多种多样的无线沟通，并获得了多种多样的沟通。 经济。被动无线系统（通常只接收非常淡淡的信号），例如射电天文学和地球探索遥感，在经济和科学上对地球环境，我们的太阳系和宇宙（例如，天气预报，对太阳能的观察，可能影响基础设施和生命的太阳能观察）提供了重要的观察。两种类型的系统都起着至关重要的作用，为人类的增长起着至关重要的作用，因此需要适应其进步。但是，它们的频谱要求在很大程度上正在增长和冲突，而从活动系统到被动系统的射频干扰（RFI）越来越关注。这需要新的频谱访问和共享范式，可以满足未来的需求。该项目提出了细胞无线通信（CWC）和射电天文学系统（RAS）之间的范式。该项目开发了CWC和RAS之间的新型时间和频频访问，这不仅可以解决频谱要求冲突，而且还可以增强两个系统的频谱访问机会。该项目并没有依靠RAS望远镜的地理隔离来避免RFI，而是通过使用大量分布式辅助射电望远镜（DARTS）引入了CWC和RAS之间的地理共存范式。非常大规模的飞镖将抑制RFI问题，并有可能使RAS的能力产生量子飞跃。此外，该项目还开发了新型的自适应电路和信号处理算法，以有效地处理RFI问题。简而言之，该项目通过它们之间的协调开发了CWC和RAS频谱访问频谱的跨学科和互惠的技术解决方案。 CWC可以获得更多的频谱访问机会，这将使更多的无线服务/应用程序和新的商机，从而扩大和丰富国民经济。 RAS将获得更多的频谱访问机会并增强天文观察能力，从而加速其对基础科学，宇宙知识的贡献以及通过太空环境信息对地球上生命的保护。
