What is the fundamental requirement of OFDM? It has orthogonality. The frequency spacing is 1/T which leads the signal to be orthogonal. If the bit time of the carrier is T, then the base frequency must be chosen to be a multiple of 1/T. OFDM Multiple carrier signals at different frequencies that send some bits on each channel. OFDMA Like OFDM, except that it is a multi-user version. Multiple access is achieved by assigning subsets of subcarriers to individual users. SC-F...
