The rapid increase in the quantity and capability of consumer mobile wireless devices has accelerated the growth in demand for radio frequency spectrum. In recent years, to address congestion in allocated spectrum bands and allow for continued growth opportunities, national and international regulators have taken steps to identify new spectrum for use by mobile wireless services such as cellular and Wi-Fi. Unfortunately, myriad other systems and services already make use of spectrum in the frequency ranges that could be useful for mobile wireless. With limited opportunities to open up new unencumbered bands for spectrum hungry mobile wireless services, regulators are turning to spectrum sharing among increasingly broad system types as their only recourse. In two recent examples, the US Federal Communications Commission auctioned for cellular services two bands used by meteorological satellite services and US Navy radars, raising concerns about the interference to the incumbent services as well as the ability of incumbent services to maintain the privacy of their operations. This project explores a general framework for architecting spectrum sharing systems and examining design trades rigorously. The design goals of a spectrum sharing system will fall into three categories, namely, performance, privacy and complexity. The project will conduct formal optimization analysis to study the allocation of resources (time, frequency and power) among the various networks in terms of the resulting utility of the spectrum for those networks to maximize performance subject to interference constraints. Since the operational information about wireless systems needed to effect spectrum sharing, such as locations, frequencies, time of use, and susceptibility to interference, may be considered sensitive, this project will answer whether, under what conditions, and how a spectrum sharing system can be designed to protect a critical level of privacy for the systems it enables. To do so, the project will consider the scope of operational scenarios, adversary exploitation techniques, and obfuscation strategies to protect privacy, developing relevant metrics for the analysis.

消费者移动无线设备数量和容量的快速增长加速了对射频频谱的需求增长。近年来，为了解决已分配频段的拥堵问题，并考虑到持续的增长机会，国家和国际监管机构已采取措施，确定新的频谱，供蜂窝和Wi-Fi等移动无线服务使用。不幸的是，无数其他系统和服务已经在使用对移动无线有用的频率范围内的频谱。由于为急需频谱的移动无线服务开辟新的未受限制的频段的机会有限，监管机构正转向越来越广泛的系统类型之间的频谱共享，作为他们唯一的手段。在最近的两个例子中，美国联邦通信委员会(US Federal Communications Commission)拍卖了气象卫星服务和美国海军雷达使用的两个频段的蜂窝服务，这引发了人们对现有服务受到干扰以及现有服务是否有能力维护其运营隐私的担忧。这个项目探索了一个总体框架，用于设计频谱共享系统和严格审查设计交易。频谱共享系统的设计目标将分为三类，即性能、隐私和复杂性。该项目将进行正式的优化分析，以研究资源(时间、频率和功率)在各种网络之间的分配，从而使这些网络的频谱效用最大化，从而在受到干扰限制的情况下最大限度地提高性能。由于实现频谱共享所需的有关无线系统的操作信息(如位置、频率、使用时间和对干扰的敏感性)可能被认为是敏感的，因此本项目将回答在什么条件下以及如何设计频谱共享系统以保护其启用的系统的关键隐私级别。为此，该项目将考虑操作场景的范围、对手利用技术和混淆策略以保护隐私，并为分析制定相关指标。
