摘　　要：滤波器组多载波技术抗多径衰落能力很强,能够平衡高速传输与均衡接收复杂度二者之间的矛盾,是未来宽带无线通信的发展方向之一。从已获广泛应用的正交频分复用技术出发,简述滤波器组多载波传输技术基本原理及框图,给出现存问题。在此基础上总结它们与多输入多输出、码分多址以及认知无线电系统的技术融合,并对滤波器组多载波技术发展做出展望。Filter Bank based Multicarrier technique has a strong ability of anti-multipath fading,and provides a better solution to the contradiction between the high-speed wireless data transmission and sophisticated equalization processing technique.Filter Bank based Multicarrier has been seen as a developing direction of the next-generation broadband wireless communication.This paper describes the basic principles of FBMC and OFDM,as well as their advantages and disadvantages.Based on the description of the principles,the combination of these two techniques,MIMO,CDMA and CR are discussed.Finally,the article makes a prospect for the development of multicarrier technology.
