通信导航一体化技术研究进展

近年来,大众对泛在位置服务的需求不断增长,卫星导航在室内等场景下覆盖能力不足,已无法满足人们的需求。由于通信信号覆盖范围广、用户数量大、信号频带宽,将通信信号用于定位可成为卫星导航的有效补充。在此背景下,随着通信和定位技术的快速发展,通信和导航的耦合程度不断加深,产生了通信导航一体化技术(CPIT),并成为了国内外的研究热点。通信系统中毫米波、多入多出(MIMO)、波束成形等技术为CPIT的发展带来了新的契机。首先介绍了CPIT的演进过程;然后就CPIT中的关键技术进行了总结并分析了其研究现状;最后对CPIT的发展进行了展望。

Research Progress of Communication-Positioning Integrated Technology

In recent years, the public''s demand for location based services has been growing. Moreover, the satellite navigation is unable to meet people''s needs because it can''t cover the indoor areas. As the communication signal has a wide range of coverage, a large number of users and a wide signal frequency band, it can be an effective supplement for satellite navigation in the way of positioning. With the rapid development of communication and positioning technology, the coupling degree of communication and positioning is being deepened, which leads to the communication-positioning integrated technology (CPIT) and has become a hot research topic worldwide. In communication system, millimeter wave, multiple input multiple output (MIMO), beam forming and other technologies bring new opportunities for the development of CPIT. Firstly, this paper introduces the evolution process of CPIT. Then, the key technologies of CPIT are summarized, and their current research situations are also analyzed. At last, this paper prospects the development of the CPIT.
