摘　　要：提出了一种适合6G的统一波形架构的波形方案广义滤波器组-正交频分复用波形(GFB-OFDM,Generalized Filter Bank Orthogonal Frequency Division Multiplexing)。通过多个功能模块的组合,模块化设计了GFB-OFDM发射端的处理过程,也详细介绍了GFB-OFDM通过这些模块进行适配的参数配置,可以变换为多种现有的主要候选波形,包括:循环前缀正交频分复用(CP-OFDM,Cyclic Prefix OFDM)、滤波器组正交频分复用(FB-OFDM,Filter Bank OFDM)、滤波正交频分复用(F-OFDM,Filtered-OFDM)、加窗正交频分复用(W-OFDM,WindowedOFDM)、离散傅里叶变换扩频正交频分复用(DFT-s-OFDM,Discrete Fourier Transform Spread-OFDM)、正交时频空调制(OTFS,Orthogonal Time Frequency Space)等,并且可以同时支持不同子带适配不同波形的应用场景。A novel waveform scheme termed generalized filter bank orthogonal frequency division multiplexing(GFB-OFDM)is proposed with a unified waveform architecture suitable for sixth generation(6G)mobile communication systems.Through the combination of multiple functional modules,the processing of GFB-OFDM transmitter is modularly designed.Via adaptive configuration of parameters within these modules,GFB-OFDM can be transformed into a multitude of prominent candidate waveforms,including cyclic prefix OFDM,filter bank OFDM,filtered OFDM,windowed OFDM,discrete fourier transform spread OFDM,and orthogonal time frequency space.This flexibility allows for concurrent support of diverse subbands,thereby accommodating a range of waveform applications within a single framework.
