智能优点：目前，无线通信依赖于多种无线接入技术。 然而，这些技术的不同通信能力为不同网络基础设施之间的互操作性和迁移带来了重大障碍。 网络同化对于弥合基础设施网络与终端用户通信设备多样性之间的差距是必要的。 本研究探讨了一种软件定义无线电（SDR）解决方案，通过硬件和软件重新配置，支持在单个SDR平台上并行执行多个通信系统，该平台用作基站。 在软件无线电平台的物理层和网络层要解决的研究挑战包括：（i）基于现场可编程门阵列（FPGA）技术的可重构和自适应架构，以改变软件无线电平台的通信能力;（ii）在单个软件无线电平台上并发和分时执行多个通信系统;以及（iii）移动性上下文定义和转移以支持无缝移动性。 该项目为SDR架构的发展做出了贡献，提出了SDR平台动态重配置的新机制，推进了具有可重配置SDR的无线mesh网络的协议工程研究，并为支持移动的网络中的无缝移动性提供了新方法。可重新配置的基站具有在民事灾害情况下的潜在应用，调查人员将寻求与工业界和相关研究以增加影响力。 研究的方面涉及硬件设备和软件包运行测试SDR系统提供了一个机会，让学生进行实验，了解下一代无线网络技术。 研究结果也将纳入一个新的面向项目的自适应无线通信和架构的研究生课程。

Intellectual Merit: Wireless communications, at present, relies on a multiplicity of wireless access technologies. However, the distinct communication capabilities of these technologies present significant barriers for interoperability and migration between different network infrastructures. Network assimilation is necessary to bridge the gap between the infrastructure networks and the diversity of end-user communication devices. This research investigates a software-defined radio (SDR) solution to support concurrent execution of multiple communication systems on a single SDR platform, which functions as the base station, through hardware and software reconfiguration. The research challenges to be addressed at the physical layer and the networking layer of the SDR platforms include: (i) reconfigurable and adaptive architectures based on field programmable gate array (FPGA) technology to change the communication capabilities of the SDR platform; (ii) concurrent and time-shared execution of multiple communication systems on a single SDR platform; and (iii) mobility context definition and transfer to support seamless mobility. The project contributes to the state-of-the-art of SDR architecture, proposes new mechanisms for dynamic reconfiguration of SDR platforms, advances the protocol engineering research for wireless mesh networks with reconfigurable SDRs, and provides new approaches to supporting seamless mobility in mobile networks.Broader Impact: The reconfigurable base stations have potential application to civil disaster situations and the investigators will seek collaborations with industry and related research to increase impact. Aspects of the research involving hardware devices and software packages for running tests on SDR systems provide an opportunity for students to conduct experiments and learn about the next generation of wireless network technologies. Results will also be incorporated into a new project-oriented graduate course on adaptive wireless communication and architecture.
