basic ofdm with interlever: The transmitter section converts digital data to be transmitted, into a mapping of subcarrier amplitude and phase. It then transforms this spectral representation of the data into the time domain using an Inverse Discrete Fourier Transform (IDFT). The Inverse Fast Fourier Transform (IFFT) performs the same operations as an IDFT, except that it is much more computational efficiency, and there is used in all practical systems. In order to transmit the OFDM signal the calculated time domain signal is then mixed up to the required frequency.
