摘要
将F(filter)-OFDM的框架应用在传统的LTE系统上。利用该新的波形技术,LTE系统可以支持更加灵活的参数配置,满足未来5G丰富的业务需求。通过发射机子带滤波器的设计,相邻子带间的带外泄漏(OOB)可以被大幅度抑制。接收机采用匹配滤波机制实现各个子带的解耦。最后通过实验仿真,比较OFDM系统和F-OFDM系统的误块率(BLER)性能,可以看到当存在邻带干扰时,后者通过子带滤波器对干扰的抑制,系统性能明显优于前者。
In this paper,the framework of F-OFDM is applied in the traditional LTE system.Using this new waveform,LTE sys-tem can support more flexible parameter configuration,which will meet the increasing needs of the forthcoming 5G wireless commu-nication.By designing proper transmit sub-band filters,the out of band leakage can be greatly suppressed.At the receiver,matched filter is used to realize the data decoupling of each sub-band.Finally,the block error rate（ BLER） performance of OFDM and F-OFDM is compared through the computer simulation.The results show that the F-OFDM system performances better than the OFDM one in the presence of the adjacent band interference.
