The first thing you must change for understanding why IFFT is used for OFDM is to forget about time and frequency domains. As the name states OFDM is a technique about frequency domain multiplexing. When you think in FDM you'll have several channels modulated with a guard interval between then to prevent interference. dr. dilip bearelly hamilton ohio
