项目摘要
The objective of this project is to develop a Multi-Input Multi-Output (MIMO) aware cooperative Dynamic Spectrum Access framework, termed McDysa, which enables multiple primary users and multiple secondary users to cooperate in dynamic spectrum sharing. By exploiting the underlying cognitive radio and MIMO techniques, McDysa is expected to achieve significant gains on spectrum efficiency while providing substantial enhancements to physical layer security as well. The technical merit and impact of this project are both fundamental and applied, including new problems, algorithms, and methodologies. The McDysa architecture considers multiple simultaneous primary- and secondary-user transmissions by exploiting MIMO techniques. A number of problems studied in the project may foster the development of novel techniques and methodologies toward MIMO-aware dynamic spectrum access. Examples include the novel problem of MIMO-enabled relay selection, insightful analysis of McDysa transmission capacity, and the consideration of secrecy capacity enhancement via friendly jamming. As many of the methodologies in McDysa leverage knowledge from other domains such as game theory, the research outcomes of this project may also motivate advancements of the corresponding domain-specific research. The broader impact of this project also extends to education. The project contains a detailed plan for disseminating the research results and for outreaching to students from underrepresented groups via various channels established in the past years. It also includes a plan for integrating undergraduate and graduate education with research through curriculum development and student involvement. Specifically, the testbed validation of McDysa can offer undergraduate and graduate students valuable hands-on experience, and is therefore an excellent educational vehicle to broaden the participation of students, especially those from underrepresented groups, in computer science research. Technically, this project defines novel problems and develops new performance-optimization techniques in the following three thrusts that are critical to MIMO-aware cooperative dynamic spectrum access: (i) Relay selection and resource sharing, which focuses on developing novel centralized and distributed relay selection and resource management algorithms based on game theory to enable multiple MIMO-empowered primary and secondary users to cooperate for joint optimization. (ii) Achievable transmission capacity analysis, which investigates the achievable transmission capacity of secondary networks and secrecy capacity of the primary network, and the usage of beamforming optimization to maximize such capacities. (iii) Secrecy capacity enhancement, which studies the usage of two friendly jamming mechanisms, cooperative jamming and artificial interference, in the design of novel beamforming techniques and interference signals for nulling the interference at the receivers, in order to enhance the secrecy capacity of the primary network. Besides the three thrusts, this project also includes the design and validation of a testbed that supports a number of experimental tasks for validating the effectiveness of approaches and methodologies developed in the project. This project also has strong societal impact as the rigorously proven solutions developed in the project can serve as guidelines and backbone for promoting and establishing more flexible spectrum access policies and regulations.
本项目的目标是开发一种多输入多输出(MIMO)感知的协作动态频谱接入框架,称为McDysa,使多个主用户和多个次用户能够在动态频谱共享中进行协作。通过利用基本的认知无线电和MIMO技术,McDysa预计将在频谱效率方面取得显著进展,同时还将大幅增强物理层安全性。这个项目的技术优势和影响既是基础的,也是应用的,包括新的问题、算法和方法。McDysa架构通过利用MIMO技术来考虑多个同时的主用户和次用户传输。该项目中研究的一些问题可能会促进新技术和方法的开发,以实现MIMO感知的动态频谱接入。例如,支持MIMO的中继选择的新问题,对McDysa传输容量的深入分析,以及通过友好干扰来增强保密容量的考虑。由于McDysa的许多方法论利用了博弈论等其他领域的知识,该项目的研究成果也可能推动相应领域特定研究的进步。该项目的更广泛影响也延伸到教育领域。该项目载有一项详细的计划,以传播研究成果,并通过过去几年建立的各种渠道向代表人数不足的群体的学生进行外展。它还包括一项通过课程开发和学生参与将本科生和研究生教育与研究相结合的计划。具体地说,McDysa的试验台验证可以为本科生和研究生提供宝贵的实践经验,因此是扩大学生,特别是那些来自代表性不足群体的学生参与计算机科学研究的极好的教育工具。在技术上,本项目在以下三个方面定义了新的问题并开发了新的性能优化技术,这三个方面对MIMO感知的协作动态频谱接入至关重要:(I)中继选择和资源共享,重点是基于博弈论开发新颖的集中式和分布式中继选择和资源管理算法,使多个授权MIMO的主用户和次用户能够协作进行联合优化。(Ii)可实现传输容量分析,其调查次级网络的可实现传输容量和主要网络的保密容量,并使用波束成形优化来最大化这些容量。(Iii)保密容量增强,研究在设计新的波束形成技术和干扰信号时使用两种友好的干扰机制--协作干扰和人工干扰,以消除接收端的干扰,以提高主网络的保密容量。除了这三个推力外,该项目还包括设计和验证试验台,该试验台支持一些实验任务,以验证项目中开发的方法和方法的有效性。该项目还具有强大的社会影响,因为项目中开发的经过严格验证的解决方案可以作为促进和建立更灵活的频谱接入政策和法规的指导方针和支柱。
