Wireless systems with different radio access technologies (RATs) are becoming packed tightly in the space of radio spectrum. The carrier frequency and channel bandwidth of these systems, however, are drastically different across the spectrum domain, e.g., the IEEE 802.11 family that operates at 900 MHz, 2.4/5 GHz, and 60 GHz (mm-wave) bands, the 3GPP 5G family that spans 6-100 GHz, and more. Therefore, radio spectrum, which has long been identified as a scarce resource, will be more crowded and diversified than ever. Swift and effective spectrum sharing requires enhanced capability and increased intelligence at the wireless devices, from innovative transmitter and receiver technologies at the physical layer, to multi-band spectrum sensing across physical and MAC layer; from mapping spectrum slices for each access request, to radical modification of medium access control (MAC) protocols. Altogether, there is a need to support a myriad of heterogeneous devices that run diverse communication standards over different frequency bands to achieve efficient spectrum and energy utilization in such huge, dynamic and disparate systems.This project mitigates the incoherent and disassociated frequency bands of the multi-RAT coexisting environments by exploiting the potential of cross-layer design from the circuits of transmitter and receiver, to the MAC layer with an innovative MAC-on-MAC spectrum control plane. This project has four major thrusts: (i) design of innovative transmitter and receiver techniques for energy-efficient multi-band spectrum monitoring, by using custom single-chip ultra-broadband (1-8 GHz) bio-inspired spectrum sensors to create a multi-band sensing solution that includes both sub-6 GHz and emerging mm-wave bands; (ii) methods to acquire complete spectrum occupancy information with a limited number of measurements from the proposed multi-band spectrum sensing circuits by exploiting matrix completion for low-cost, accurate and scalable monitoring through a learning-based sequential scheme; (iii) algorithms of obtaining a sorted ranking of paths that map a data flow to a range of spectrum slips by modeling spectrum-flow-RAT domains, finding the set of unoccupied spectrum slices, sorting out multiple recommendations from neighboring SAP control entities; (iv) creating MAC-Flow, a flow based network protocol that is capable of handling networking demands from both upper and lower layer, for both traditional user frames and for MAC-on-MAC controller processed frames for system-level performance evaluation. A holistic system-level integration of advances in spectrum detection, sensing, mapping with data flows, and implementation of MAC protocols is critical to improving spectrum utilization and user experience in coexisting wireless systems.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

带有不同无线电访问技术（大鼠）的无线系统在无线电频谱空间中被紧密地包装。然而，这些系统的载波频率和通道带宽在频谱域之间截然不同，例如，IEEE 802.11家族在900 MHz，2.4/5 GHz和60 GHz（mm-wave）频段（跨度为6-100 GHz等）中运行的IEEE 802.11家族。因此，长期以来一直被确定为稀缺资源的无线电频谱将比以往更加拥挤和多样化。迅速有效的频谱共享需要增强的能力并提高无线设备的智能，从创新的发射器和物理层的接收器技术到跨物理和MAC层的多波段光谱传感；从每个访问请求的映射频谱切片到中等访问控制（MAC）协议的根本修改。总之，有必要支持多种异质设备，这些设备在不同的频段上运行各种沟通标准，以实现如此巨大，动态和降低的系统中的有效的频谱和能量利用，以减轻该项目可减轻与循环范围内的元素相关频段的不连贯和分离的频率，从而通过循环范围内的环境来实现循环，从而跨越了循环的环境。具有创新的MAC-ON-MAC频谱控制平面的层。 This project has four major thrusts: (i) design of innovative transmitter and receiver techniques for energy-efficient multi-band spectrum monitoring, by using custom single-chip ultra-broadband (1-8 GHz) bio-inspired spectrum sensors to create a multi-band sensing solution that includes both sub-6 GHz and emerging mm-wave bands; （ii）通过通过基于学习的顺序方案利用矩阵完成来利用矩阵完成来利用矩阵完成，从而利用矩阵完成来利用矩阵完成，从而从提出的多波段频谱传感电路中获取完整的光谱信息，并通过提出的多波段频谱传感电路进行了数量有限的测量方法； （iii）通过建模频谱 - 流式rat域，找到一组未占用的频谱切片，从相邻的SAP控制实体中分析了多个建议； （iv）创建MAC-FLOW，这是一种基于流的网络协议，能够为传统的用户框架和Mac-on-on-MAC控制器处理的框架来处理上层和下层的网络需求，以进行系统级的性能评估。在频谱检测，传感，映射数据流以及MAC协议实施方面进步的整体系统水平整合对于改善频谱利用率和在共存无线系统方面的用户经验至关重要。该奖项反映了NSF的法定任务，并被认为是通过基金会的知识优点和广泛的crietia crietia crietia crietia crietia crietia crietia criteria crietia criteria crietia crietia criteria crietia crietia criteria criperia criperia criperia criperia criperia rectiria recteria recteria rection rection。
