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.

该项目的目标是通过敏捷频谱接入、自主干扰控制以及智能网络自组织和自优化，实现自主毫微微蜂窝网络更高效、更可靠的运行。该项目分为四个相互作用的主旨：1）将认知纳入毫微微蜂窝网络，以认知方式重用感知到的可用频谱； 2) 利用天线技术并基于感测到的环境条件，开发分布式、动态和协作的干扰管理方案； 3) 研究可利用毫微微蜂窝基站促进宏蜂窝传输的场景和方案，以及容量、覆盖范围和可靠性方面的潜在收益； 4) 将干扰消除纳入数据组播，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测试台，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。该系统的敏捷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程序。 PI 将通过其工业合作伙伴和行业附属计划促进技术转让。作为研究议程的补充，该项目将开展广泛的教育和推广活动，包括将研究成果纳入课程、促进弱势群体和本科生群体的发展，以及与 K-12 学校合作以提高学生的兴趣水平追求工程和数学领域的高等教育和职业生涯。
