Spectrum sharing plays a key role in realizing plans to make available new swaths of spectrum for wireless applications. The benefits of spectrum sharing cannot be fully realized without addressing interference among coexisting heterogeneous secondary networks. Although coexistence issues in the ISM bands have been studied before, the situation in the TV bands and other shared access spectrum (e.g., 3.5 GHz band) is more complex and challenging due to the signal propagation characteristics, incumbent protection rules, and the disparity of PHY/MAC strategies of secondary systems. To date, most research efforts have focused on incumbent protection, and little attention has been given to the coexistence of secondary systems in the context of spectrum sharing. The proposed research aspires to fill this void by 1. studying the viability of using stochastic neural networks for modeling and solving the CDM problem and 2. developing novel rendezvous techniques for unicast and multicast scenarios.The group plans to integrate project findings in relevant graduate courses at their respective institutions. In the second year of the project, the investigators will jointly organize a session on heterogeneous coexistence and spectrum sharing at the Virginia Tech annual Symposium and Wireless Summer School, which is an educational outreach event that serves the wireless industry. The group also proposes to give a tutorial presentation on heterogeneous coexistence and spectrum sharing at relevant conferences, including the IEEE DySPAN Conference, the flagship conference on dynamic spectrum access and spectrum sharing technologies. The group will also collaborate with our industry partners from Raytheon and Space Micro to demonstrate a sample of the proposed solutions on their spectrum-agile radio platforms.

Spectrum共享在实现计划为无线应用程序提供新的Spectrum的计划中起着关键作用。如果不解决共存的异质二级网络之间的干扰，则无法完全实现频谱共享的好处。尽管以前已经研究过ISM频段中的共存问题，但由于信号传播特征，现有保护规则以及二级系统的PHY/MAC策略的差异，电视频段和其他共享访问范围（例如3.5 GHz频段）（例如3.5 GHz频段）的情况更加复杂且具有挑战性。迄今为止，大多数研究工作都集中在现有保护上，在频谱共享的背景下，很少关注二级系统的共存。拟议的研究愿意通过1。研究使用随机神经网络来建模和解决CDM问题的生存能力，以及2。开发新颖的聚会技术，以进行单播和多播场景。小组计划在各自机构的相关研究生课程中整合项目发现。在项目的第二年中，调查人员将共同组织一次关于弗吉尼亚理工大学年度研讨会和无线暑期学校的异质共存和频谱共享的会议，这是为无线行业服务的教育外展活动。该小组还建议在相关会议上进行有关异质共存和频谱共享的教程演讲，包括IEEE DYSPAN会议，动态频谱访问旗舰会议和光谱共享技术。该小组还将与来自雷神和太空微型的行业合作伙伴合作，在其Spectrum-Agile无线电平台上展示拟议的解决方案的样本。
