Collaborative Research: EARS: Cognitive and Efficient Spectrum Access in Autonomous Wireless Networks

该项目的目标是通过灵活的频谱接入、自主干扰控制以及智能网络自组织和自优化，使自主毫微微蜂窝网络能够更高效、更可靠地运行。该项目分为四个相互作用的项目：1)将认知纳入毫微微小区网络，以认知地重用所感知的可用频谱；2)利用天线技术并基于所感知的环境条件，开发分布式、动态和协作的干扰管理方案；3)调查可利用毫微微小区来促进宏蜂窝传输的场景和方案，以及在容量、覆盖和可靠性方面的潜在收益；4)将干扰消除纳入数据多播，并开发支持多用户视频流的技术。该项目还开发了一个带有开源可编程无线平台的试验台，用于原型和评估所开发的各种技术的有效性。这项拟议的研究有可能显著提高现有和未来无线网络的容量和弹性。该系统的灵活性和弹性也将使其有助于支持对国家安全和经济重要的通信和应用程序。私人投资机构将通过其行业合作伙伴和行业附属计划促进技术转让。作为对研究议程的补充，该项目将开展广泛的教育和外联活动，包括将研究成果纳入课程，促进代表性不足的人口和本科生，并与K-12学校合作，提高学生在工程和数学领域追求高级教育和职业的兴趣水平。

The objective of this project is to enable more efficient and reliable operation of autonomous femtocell networks with agile spectrum access, autonomous interference control, as well as intelligent network self-organization and self-optimization. This project falls into four interacted thrusts: 1) Incorporate cognition into the femtocell networks to cognitively reuse the available spectrum sensed; 2) Develop distributed, dynamic and cooperative interference management schemes exploiting antenna techniques and based on sensed environmental conditions; 3) Investigate the scenarios and schemes that femtocells can be exploited to facilitate macrocell transmissions, and the potential gains in capacity, coverage and reliability; 4) Incorporate interference cancellation for data multicast, and develop techniques to support multiuser video streaming. The project also develops a testbed with open source programmable wireless platforms, for prototyping and evaluating the effectiveness of various techniques developed. The proposed research has the potential to significantly increase the capacity and resilience of existing and future wireless networks. The agility and resilience of the system will also make it instrumental to support communications and applications that are important for national security and economy. The PIs will facilitate technology transfer through their industrial partners and industry affiliate programs. Complementary to the research agenda, the project will carry out a broad range of education and outreach activities, including integration of research findings into the courses, promoting underrepresented and undergraduate populations, and engaging with the K-12 schools to raise the level of student interests in pursuing advanced education and career in the areas of engineering and mathematics.
