滤波器组多载波技术仿真性能分析

基于滤波器组的多载波调制技术是第5代移动通信系统(5 G)研究的关键技术之一。与传统的调制技术相比滤波器组多载波技术具有不需要插入循环前缀、较低旁瓣等优点，其技术发展尚处于探索阶段。使用滤波器组多载波技术调制方式实现信号调制主要有两种方式，其中之一的 FBMC是在 IFFT的基础上使用原型滤波器在帧结构水平上对信号进行滤波，因此重点是设计出滤波器组对帧信号的合理处理方式。

Filter bank multicarrier technique simulation performance analysis

Filter bank based multicarrier technique is one of pivotal techniques of 5G. Compare to traditional modulation,Filter bank based multicarrier technique has some advantages including performing without CP and lower sidelobe.This technique is still developing.There are twoclasses of modulated filter banks,FBMC filter the signal at the level of frame on the basis of IFFT.So the important thing is reasonable design of processing fame signal by filter banks.
