Many of the innovative recent wireless devices rely on the unlicensed spectrum, spurred by its openness to new uses and users. At the same time, vast amounts of spectrum are still exclusively licensed to services with sparse demand and to standards that use antiquated technologies. The current way of sharing thelimited unlicensed spectrum that we do have is also far from perfect: devices suffer from very limited range even when there are no interference problems, and severe performance degradation when their local spectrum is shared by users from heterogeneous systems.We look at spectrum management through the lens of the traditional 3 R's of resource use: Reduce, Reuse and Recycle. While Reduce has received by far the most attention from the engineering community, research in Recycle and Reuse is at a much more primitive state. But it is progress in the latter two areas that will be critical for the open and efficient sharing of the spectrum as a whole. Spectrum Recycling refers to fostering sharing and improving overall spectral efficiency while maintaining backward-compatibility with users oflegacy systems like analog broadcast and cellular standards. Spectrum Reuse refers to the collaborative coexistence of multiple wireless systems, using limited interaction to share the spectrum fairly andefficiently. The proposed research takes a broad, systematic and inter-disciplinary approach to the fundamentals of these two problem areas, combining ideas from physical layer wireless communications,multiuser information theory and distributed coding, resource allocation and game theoretic analysis.

最近许多创新的无线设备都依赖于未经许可的频谱，这得益于其对新用途和新用户的开放。与此同时，大量频谱仍然专门授权给需求稀少的服务和使用过时技术的标准。当前共享我们所拥有的有限未授权频谱的方​​式也远非完美：即使不存在干扰问题，设备的范围也非常有限，并且当来自异构系统的用户共享其本地频谱时，性能会严重下降。通过传统的 3R 资源使用视角进行频谱管理：减少、再利用和回收。虽然Reduce 迄今为止受到了工程界的最多关注，但回收和再利用方面的研究还处于更为原始的状态。但后两个领域的进展对于整个频谱的开放和高效共享至关重要。频谱回收是指促进共享和提高整体频谱效率，同时保持与模拟广播和蜂窝标准等传统系统用户的向后兼容性。 频谱复用是指多个无线系统协作共存，利用有限的交互来公平、高效地共享频谱。本研究采用广泛、系统和跨学科的方法来研究这两个问题领域的基础知识，结合了物理层无线通信、多用户信息论和分布式编码、资源分配和博弈论分析的思想。
