Abstract
Provided are an orthogonal frequency division multiplexing (OFDM) time domain windowing method and apparatus. The method includes: current OFDM symbol data is parsed according to a configuration task, and an inverse fast fourier transform (IFFT) processing is performed on the current OFDM symbol data to obtain IFFT data; a cyclic prefix (CP) is added to the IFFT data; and a time domain windowing mode of the current OFDM symbol data is determined according to the configuration task, a windowing operation is performed on IFFT data added with the CP according to the determined time domain windowing mode, and IFFT data after performing the windowing operation is output.
