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

该项目的目标是使自主毫微微蜂窝网络能够更有效和可靠地运行，具有灵活的频谱接入、自主干扰控制以及智能网络自组织和自优化。该项目福尔斯分为四个相互作用的重点：1）将认知技术引入到毫微微蜂窝网络中，以认知地重用感知到的可用频谱; 2）利用天线技术和基于感知到的环境条件，开发分布式、动态和协作的干扰管理方案; 3）研究可以利用毫微微小区来促进宏小区传输的场景和方案，以及容量的潜在增益，覆盖面和可靠性; 4）为数据多播引入干扰消除，并开发支持多用户视频流的技术。该项目还开发了一个具有开源可编程无线平台的测试平台，用于原型设计和评估所开发的各种技术的有效性。 拟议的研究有可能显着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至关重要的通信和应用。PI将通过其工业合作伙伴和工业联盟计划促进技术转让。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，包括将研究成果融入课程，促进代表性不足和本科生群体，并与K-12学校合作，提高学生在工程和数学领域接受高等教育和职业的兴趣。

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.
