Title
(EN) Data transmission method, device and equipment, and storage medium
(ZH) 数据传输方法、装置、设备和存储介质
Abstract
(EN) The invention provides a data transmission method and device, equipment and a storage medium, and the method comprises the steps: respectively carrying out the DFT (discrete Fourier transform) of M points of first time domain data, and obtaining frequency domain data; performing filtering operation on the frequency domain data to obtain filtered frequency domain data; performing N-point inverse discrete Fourier transform (IDFT) on the filtered frequency domain data to obtain second time domain data; and transmitting the second time domain data on a physical resource.
(ZH) 本申请提供一种数据传输方法、装置、设备和存储介质,包括:对第一时域数据分别进行M点离散傅里叶变换DFT,得到频域数据;将所述频域数据进行滤波操作,得到滤波后的频域数据;将所述滤波后的频域数据进行N点离散傅里叶逆变换IDFT,得到第二时域数据;将所述第二时域数据在物理资源上传输。
