摘要
近年来,光载无线通信(RoF)技术已经成为宽带光通信接入网络领域的研究热点,备受业界关注。该技术充分利用了光纤传输的海量带宽和无线通信灵活覆盖的应用优势。在RoF技术的演进发展过程中,多维多阶调制方式能提升系统频带利用率和降低信号收发成本,因此具有重要的科研意义和实用价值。文章综述了传统幅度调制、典型多维多阶调制和若干代表性新型多维多阶调制技术的研究进展,并对RoF系统中多维多阶调制技术的应用前景进行了简略分析。
Recently,Radio over Fiber(RoF)technology has become a hot research topic in the broadband communication access network field and has attracted much attention in the industry.This is mainly because the technology makes full use of the massive bandwidth of optical fiber transmission and the application advantages of flexible coverage of wireless communication.In the evolution and development of RoF technology,multi-dimensional multi-order modulation has important scientific research significance and practical value because it can improve the system bandwidth utilization and reduce the signal transmission and receiving cost.This paper summarizes the research progress of traditional amplitude modulation,typical multi-dimensional multi-order modulation and some representative new multi-dimensional multi-order modulation technologies.We also briefly analyzes the application prospect of multi-dimensional multi-order modulation technology in RoF system.
