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的数量和能力的迅速增加，加速了对射频频谱需求的增长。近年来，为了解决分配的频谱频段的拥堵并允许持续的增长机会，国家和国际监管机构已采取措施确定新的频谱，以供移动无线服务（例如Cellular和Wi-Fi）使用。不幸的是，其他无数系统和服务已经在可能对移动无线有用的频率范围内使用频谱。由于有限的机会开放新的无束缚乐队用于饥饿的移动无线服务，因此监管机构正在转向越来越广泛的系统类型的频谱共享，这是他们唯一的追索权。在最近的两个示例中，美国联邦通信委员会拍卖了蜂窝服务，由气象卫星服务和美国海军雷达使用的两个频段，引起了人们对现任服务的干扰以及现任服务维护其业务隐私的能力的担忧。该项目探讨了架构频谱共享系统并严格检查设计交易的一般框架。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。该项目将在各个网络中研究资源（时间，频率和功率）的正式优化分析，以这些网络的频谱实用性为止，以最大程度地提高性能受到干扰约束。由于有关实现频谱共享所需的无线系统的操作信息，例如位置，频率，使用时间和对干扰的敏感性，因此可以将其视为敏感，因此该项目将回答是否可以在什么条件下以及如何设计频谱共享系统来保护该系统的关键隐私水平。为此，该项目将考虑操作场景，对手剥削技术的范围，以及保护隐私的混淆策略，并为分析开发相关的指标。
