摘　　要：国家973计划项目"多域协同宽带无线通信基础研究"于2007年立项。该项目围绕国家"新一代宽带无线通信网络"重大专项等发展需求,探索从根本上提高频谱资源利用有效性的基础理论,力争实现宽带无线通信技术体系及核心关键技术的创新。本文介绍了该项目的立项背景、科学问题和研究课题设置,以及项目在多域协同通信系统体系框架、低信噪比信号同步、多极化天线小型化、异构网络融合等方面取得的主要创新研究成果。最后,对该项目下一阶段的研究工作进行了展望。National 973 Project ＂Fundamental Research on Multi-Domain Collaboration for Broadband Wireless Communications＂ started in 2007. This project focuses on the development need of the National S＆T Major Program ＂New Generation Broadband Wireless Communication Networks＂, exploring fundamental theory to improve the effectiveness of spectrum utilization while achieving innovations in broadband wireless communication architecture and key technologies. This article introduced the background, scientific problems and scheduled research subprojects of the project. Some innovative research results in multi-domain collaborative communication system architecture, signal synchronization in low SNR environment, miniaturization of multipolarization antennas and amalgamation of heterogeneous networks were summarized. Finally, the next stage research of the project was outlined.
