中文摘要:
      Filtered-OFDM系统通过引入子带滤波器改进了OFDM波形,可灵活地根据业务场景来动态地选择和配置波形参数。目前还没有较为明确的子带滤波器设计方法,本文选取MATLAB中FDAtool工具箱来进行滤波器的设计,并以Filtered-OFDM下行链路为例,选取其中两个子带分别加入适合各自带宽的Hanning窗子带滤波器。通过仿真改变滤波器的阶数和保护带宽研究了子带接收端误码率的变化情况,给出了子带滤波器的设计方法和参数分析。
英文摘要:
      The Filtered-OFDM system improves the OFDM waveform by adding subband filters and can flexibly select and configure the waveform parameters according to the business scenario. There is no clear subband filter design method, In this paper, we choose the FDAtool toolbox in MATLAB to design the filter and take the Filtered-OFDM downlink as an example, select the two sub-band, for the respective bandwidth to join the Hanning window filter. The change of the bit error rate of the subband receiver is studied by changing the order of the filter and the size of the protection bandwidth. Finally, the design method and parameter analysis of the subband filter are given.
