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.

电信行业正处于重大结构变革的边缘。从历史上看，该行业的监管机构已经为可用频谱内定义良好的频段的使用分配了许可证。与其他商品不同，频谱的二级市场从未发展起来。技术限制以及法律和规章的限制可能是造成这一事实的原因之一。今天的证据清楚地表明，频谱的利用相对不足。“认知无线电网络”（CRN）是无线通信的一种新范式，旨在更有效地利用频谱。这个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。S以分布式方式管理干扰的能力，无需主要用户的合作。在这里，研究任务包括从信号处理和算法的角度分析各种基于价格的动态频谱分配方案，这些方案适用于各种监管限制下的各种CRN场景。第二个相关问题涉及频谱二级市场的设计。考虑到特定的频谱共享技术和卖方（即主要用户/主要网络服务提供商（NSP））和买方（即认知用户）的相关行为，本研究调查了各种设计选择的分析。建议的工作目标是建立新的模式，以(i)促进广泛CRN范围内的分布式频谱共享和频谱决策，以及（ii）为二级频谱市场的运作提供额外的见解，这可能对规管设计有用。
