摘要
通用滤波多载波(Universal Filtered Multi-Carrier,UFMC)是一种新型的多载波技术,是公知的5G多载波体制,结合了滤波正交频分复用(Filtered Orthogonal Frequency Division Multiplexing,F-OFDM)和滤波器组多载波(Filter Band MultiCarrier,FBMC)的一些优点的多载波传输方案。但是,经典的UFMC发射机结构存在计算复杂度高,实现难度大等问题。文章旨在将UFMC发射机结构进行优化设计,降低UFMC发射机的计算复杂度。
Universal Filtered Multi-Carrier(UFMC) is a new type of multi-carrier technology. It is a well-known 5 G multi-carrier system combined with some advantages of Filtered Orthogonal Frequency Division Multiplexing(F-OFDM) and Filter Band Multi-Carrier(FBMC). However, the classical UFMC transmitter structure has problems such as high computational complexity and difficulty in implementation. This paper aims to optimize the UFMC transmitter structure and reduce the computational complexity of the UFMC transmitter.
