摘要
FBMC滤波器多载波中的码间和子载波间的干扰是由邻近的子载波引起的,在高速运动的情况下,存在着频率选择性衰减和时选择性衰减的问题。文章所使用的多载波滤波器组FBMC技术,其旁瓣小,频谱效率高,抗选择性衰落性能好。文章以FBMC为例,介绍了基于FBMC中的原型滤波器和FBMC的基础架构的设计方法,为了消除FBMC滤波器组的固有干扰,并对其进行了深入的分析。
The interference between the code and between the subcarrier waves in the FBMC filter is caused by the adjacent subcarrier.In the case of high-speed motion,there is the problem of frequency-selective attenuation and time-selective attenuation.The multi-carrier filter set FBMC technology used in this paper has a small side flap,high spectrum efficiency,and good anti-selective fading performance.Taking FBMC as an example,the design method based on FBMC is introduced in order to eliminate the inherent interference of FBMC filter set.
