 English term or phrase: add to be the sum of the original waveform Each sub-carrier transmits 250,000 OFDM symbols. Fast fourier transforms（快速傅立叶变换） are used to create the waveform. A fourier transform (FT) separates a waveform or function into sinusoids waves（正弦波） of different frequency which add to be the sum of the original waveform.
