The telecommunications industry is on the verge of major structural change. Historically, the industry's regulator has allocated licenses for the utilization of well-defined bands within the available spectrum. Unlike other commodities, no secondary market for the spectrum has ever developed. Technological limitations as well as legal and regulatory constraints may have contributed to this fact. Today the evidence clearly points to a situation of relative under-utilization of the spectrum. A "cognitive radio network" (CRN) is a new paradigm for wireless communications aimed at enabling a more efficient use of the spectrum. This research project focuses on two significant technical and regulatory issues which must be resolved to ensure successful deployment of cognitive radio networks. The first issue relates to the network?s ability to manage interference in a distributed fashion without cooperation from the primary users. Here, the research tasks include the analysis, from a signal processing and algorithmic point of view, of various price-based schemes for dynamic spectrum allocation in a broad range of CRN scenarios under a variety of regulatory restrictions. The second relevant issue pertains to the design of a secondary market for the spectrum. The research investigates the analysis of various design choices taking into account specific spectrum sharing techniques and the associated behavior of sellers (i.e. primary users/primary network service providers (NSP)) and buyers (i.e. cognitive users).The proposed work targets new models to (i) facilitate distributed spectrum sharing and spectrum decision in a broad range of CRN, and to (ii) provide additional insights into the operation of a secondary spectrum market which could prove useful for regulatory design.

电信业正处于重大结构变革的边缘。从历史上看，行业监管机构已经分配了许可证，用于使用可用频谱内定义明确的频段。与其他商品不同，频谱的二级市场从未发展起来。技术限制以及法律的和规章的限制可能促成了这一事实。今天的证据清楚地表明，频谱利用率相对不足。“认知无线电网络”（CRN）是无线通信的新范例，旨在实现更有效地使用频谱。该研究项目的重点是两个重要的技术和监管问题，必须解决，以确保成功部署认知无线电网络。 第一个问题与网络有关。的能力，以分布式的方式管理干扰，而无需来自主要用户的合作。在这里，研究任务包括分析，从信号处理和算法的角度来看，各种基于价格的方案，在各种监管限制下的广泛的CRN场景中的动态频谱分配。第二个相关问题涉及频谱二级市场的设计。 该研究调查了各种设计选择的分析，同时考虑到特定的频谱共享技术和卖方的相关行为（即主要用户/主要网络服务提供商）和买家（即认知用户）。所提出的工作将新模型作为目标，以（i）促进广泛范围的CRN中的分布式频谱共享和频谱决策，以及（ii）就第二频谱市场的运作提供额外的见解，这对规管设计可能会有帮助。
