WebNov 26, 2013 · Reviewing the utter basics: An FFT takes a signal in the time domain and converts it ( transforms it, you might say) to the frequency domain. A 60Hz sinewave (time domain) transforms to a spike at 60Hz (frequency domain). If there are spikes at 120Hz, 180Hz, and so on, then you know there’s distortion. Webof OFDM lies with how the system handles the multipath interference at the receiver end. OFDM is multicarrier modulation (MCM) technique which provides an efficient means to handle high speed data streams on a multipath fading environment that causes ISI. Normally OFDM is implemented using FFT and IFFT’s.
