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.

频谱共享在实现为无线应用提供新频谱的计划中发挥着关键作用。如果不解决共存异构辅助网络之间的干扰问题，就无法充分实现频谱共享的好处。尽管之前已经研究过 ISM 频段的共存问题，但由于信号传播特性、现行保护规则以及不同频段的差异，TV 频段和其他共享接入频谱（例如 3.5 GHz 频段）的情况更加复杂且更具挑战性。辅助系统的 PHY/MAC 策略。迄今为止，大多数研究工作都集中在现有保护上，而很少关注频谱共享背景下二级系统的共存。拟议的研究旨在通过 1. 研究使用随机神经网络建模和解决 CDM 问题的可行性以及 2. 开发用于单播和组播场景的新型交会技术来填补这一空白。该小组计划将项目成果整合到相关的研究生课程中在各自的机构。在该项目的第二年，研究人员将在弗吉尼亚理工大学年度研讨会和无线暑期学校联合组织一次关于异构共存和频谱共享的会议，这是一项服务于无线行业的教育推广活动。该小组还建议在相关会议上进行关于异构共存和频谱共享的教程演示，包括动态频谱接入和频谱共享技术的旗舰会议 IEEE DySPAN 会议。该小组还将与雷神公司和 Space Micro 的行业合作伙伴合作，在其频谱捷变无线电平台上展示拟议解决方案的示例。
