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起着关键作用。如果不解决共存的异构次级网络之间的干扰，就不能完全实现频谱共享的益处。尽管之前已经研究了ISM频带中的共存问题，但是TV频带和其他共享接入频谱（例如，3.5由于信号传播特性、现行保护规则以及次系统的PHY/MAC策略的差异，因此，（GHz频带）更复杂且更具挑战性。到目前为止，大多数研究工作都集中在现任保护，很少注意到在频谱共享的背景下，二次系统的共存。拟议的研究旨在填补这一空白1。研究使用随机神经网络建模和解决CDM问题的可行性和2。为单点传送和多点传送的场景开发新的会合技术。2该小组计划将项目的研究成果整合到各自机构的相关研究生课程中。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，这是一次服务于无线行业的教育推广活动。该小组亦建议在相关会议上，包括IEEE DySPAN会议，即有关动态频谱接入和频谱共享技术的旗舰会议上，就异构共存和频谱共享作专题演讲。该小组还将与Raytheon和Space Micro的行业合作伙伴合作，在其频谱敏捷无线电平台上展示拟议解决方案的样本。
