The dynamic and uneven wireless network traffic load at different time instants and geographical locations has led to substantial underutilization of some spectrum bands while severely crowding others. This project investigates a number of fundamental and challenging technical issues that arise from broadband spectrum trading for achieving superior technical, economic, and social values of spectrum use. The project is an interdisciplinary research effort across mathematics and wireless network technologies. With respect to wireless technologies, this research project outcomes can significantly improve spectrum efficiency and user experience, while benefiting many real-life needs, such as public safety, telemedicine, and social services. On mathematics, the research effort will lead to the formulation of more interesting problems with real world applications and the discovery of new tools for solving such problems. As a comprehensive investigation to overcome technical challenges that arise from broadband spectrum trading, the project tasks focus on three inter-related key research directions: 1) new graph theory problems, 2) new graph-based resource allocation and utility optimization, and 3) physical layer techniques and utility design. Specifically, the project considers new problems on judicious partitions of graphs and new problems on optimal disjoint paths in weighted graphs using minimum-edge-weight path utility. New solutions and tools developed for such problems can then be applied and generalized for solving various resource allocation and utility optimization problems in broadband spectrum trading. Furthermore, the project addresses new fundamental physical layer issues that arise from spectrum trading. These implementation issues include broadband channel estimation, dynamic pilot placement, interference limited pilot power control, and low complexity broadband spectrum sensing. To establish utility functional curves and to develop means for modeling parametric effects in fine-granularity for more effective broadband spectrum trading, the project applies group-theory-based methodologies to design and carry out detailed tests and analysis in order to fine-tune effective utility functions that incorporate user experience and satisfaction. The research results are also expected to lead to strong social impacts and to provide better technical insights and effective guidelines on governmental regulatory policymaking and technological development regarding broadband spectrum trading for wireless communications.

不同时间和地理位置的动态和不平坦的无线网络交通负载导致某些频谱频段的实质性不足，同时严重拥挤了其他频段。该项目调查了许多基本和挑战性的技术问题，这些问题是由宽带光谱交易引起的，以实现频谱使用的卓越技术，经济和社会价值。该项目是跨数学和无线网络技术的跨学科研究工作。关于无线技术，该研究项目成果可以显着提高频谱效率和用户体验，同时使许多现实生活中的需求（例如公共安全，远程医疗和社会服务）受益。关于数学，研究工作将导致现实世界应用和发现解决此类问题的新工具的更有趣的问题。作为克服宽带频谱交易引起的技术挑战的全面调查，项目任务集中在三个相互关联的关键研究方向上：1）新的图理论问题，2）新的基于图的资源分配和实用性优化，以及3）物理层技术和实用程序设计。具体而言，该项目考虑了使用最小范围的路径实用程序，在加权图中的最佳分离路径上明智地分区和新问题上考虑了新问题。然后可以应用和推广为此类问题开发的新解决方案和工具，以解决宽带光谱交易中的各种资源分配和实用性优化问题。此外，该项目解决了频谱交易引起的新的基本物理层问题。这些实施问题包括宽带通道估计，动态飞行员放置，干扰有限的飞行员功率控制和低复杂性宽带光谱传感。为了建立效用功能曲线并开发用于对细粒度的参数效应建模以进行更有效的宽带光谱交易的方法，该项目将基于组理论的方法应用于设计和进行详细的测试和分析，以微调有效的实用程序功能，以融入用户体验和满意度。预计该研究结果还将带来强烈的社会影响，并提供有关政府监管决策和技术发展的更好的技术见解和有效的指南，涉及有关无线通信的宽带光谱交易。
