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.

该项目的目的是启用具有敏捷频谱访问，自主干扰控制以及智能网络自组织和自我优化的自主femtocell网络的更高效和可靠的操作。该项目分为四个相互作用的推力：1）将认知纳入fomtocell网络中，以认知重复使用可用的频谱； 2）开发分布式，动态和合作的干扰管理方案，利用天线技术并基于感知的环境条件； 3）调查可以利用femtocells的情况和方案，以促进麦克罗克尔的传播以及能力，覆盖范围和可靠性的潜在增长； 4）合并了用于数据多播的干扰取消，并开发了支持多用视频流的技术。该项目还开发了一个具有开源可编程无线平台的测试台，用于原型制作和评估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能力和韧性。该系统的敏捷性和弹性也将使支持对国家安全和经济很重要的通信和应用程序起着重要作用。 PI将通过其工业合作伙伴和行业会员计划促进技术转移。互补的研究议程将进行广泛的教育和外展活动，包括将研究结果融入课程，促进代表性不足和本科生的人口，并与K-12学校互动，以提高学生在工程和工程和数学领域追求高级教育和职业方面的学生利益水平。
